2.   Liaison Activities.
2.1  X3J11 + ANSI
MacDonald (vice chair X3J11) two parties in X3J11 have funding issues to
resolve with X3.
Discussion over MacDonald's voting status due to SGI Cray merger, no need for
action until next meeting.
It has been confirmed that Jaeschke  will serve as chair for next 3 years.
(Pause for large round of applause!! )
2.2  WG14 + ISO/SC22
PJP received a letter from ISO detailing actions permissible with regard to
web pages and making RR's (Record of Responses) available on web. Record of
response is acceptable to appear on web.

RR can go on the web with immediate effect. Need to produce rationale and
formal request for permission to publish TC's on the web.

Farance, Meyers desire that TC should be available on the web.

*** Keaton and Plauger will make  TC's and RR's available on the private web
page.
(Done by close on 28 June) Discussion about distribution of standards on web
and commercial issues. Plum believes - IEEE now supply a service to provide
browser and document on web.

*** Farance will draft words of request to SC22 for Convenor requesting
permission to post TC's on the web.
Proposal to empower the WG14 Convenor to request SC22 to make TC's available

2.3  X3J16 /WG21 (C++)

Plum  Last meeting Santa Cruz March 16. Main problem is controversy about
template model. Stockholm is in 2 weeks time. Hoping for a CD vote at Stockholm.

Sam Harbison is stepping down as Convenor, Plum has been proposed as new
Convenor. If Plum becomes Convenor,   WG14 should  consider a new liaison,
and Plum will have to give up IR status.

Kwan asked about extended literal identifiers - will they be in the next C++
working paper .i.e. C++ will support multibyte characters in identifier
names.
Plum - yes
MacDonald, does WG21 have a target date ? Plan is to have  CD  after next
meeting, DIS a year later and a standard at the end of  98

2.4  WG15 (POSIX)
Simonsen- forwarding WG14 papers to POSIX.
Walls- networking people were of defining things similar to inttypes.h
(Posix.1.g)
Kwan could Simonsen check on if POSIX requires prototypes.
2.5  WG20
Last meeting was in Kyoto April 1996.  WG20 liaison report available as WG14
N576/X3J11 96-040 Putting forward a TR based on C and POSIX
internationalization work.

Document PDTR 10176 Guidelines for the Design of Programming Languages, is
out for voting at the moment and has obtained something like 120 comments.
Document was sent out for PDAM, document is already available on DS WG14 web
page.
TR 11017 Framework for Internationalization, out for DTR ballot.

***  Benitio, Simonsen, Feather and Farance to review the above document.

Producing a sorting spec with an API.

Walls - voiced concern over compatibility with C wide characters
Plum - key issue any use of new sorting algorithm is a new locale hence no
requirement on existing locale.

Discussion over MSE and X/Open specs that POSIX; they appear to be in
conflict with MSE.

Plum reminded the committee C++ points to MSE and hence these issues effect
C++ Walls, X/Open plan to align with MSE.

Simonsen WG20
Producing a standard for locale and char maps. Will include a new locale
covering all of ISO 10646

Simonsen WG20
Approval of  work item on internationalization API failed on voting, not sure
what will happen  CEN want the work to materialize, so it may happen via a
different route.
2.6  Other Liaison Activities
Farance been in discussion with WG11 (LIA). Wish to discuss exceptions issues
and feedback to WG11.

Tydeman what happened to comments- Farance most were applied

MacDonald - FORTRAN compatibility with C. Big issue is mapping FORTRAN types
to C types.
Topics of interest, no binding to a complex type if there is an imaginary
type. i.e. they are looking for a one to one binding.

Simsonsen.

CEN, TC 204 have completed a registry standard on locales and char maps.

Farance
Information infrastructures panel. looking for response from X3- talk to
Farance off-line.

3.   Redactors Report N553 & N559, N556
Farance:
Summary page attached to N559 (draft 6 of C9X) explains the changes and
resolved issues.
Tydeman - examples on empty macros appears to be absent there was also some
other text that should have been deleted.
(page 65 handwritten of pre Amsterdam mailing)

Some discussion regarding what issues had made it into the draft.

Benito suggests all those that have lists of issues get together and form a single
list of items that need checking. During DR's an editorial group will be formed.

Walls, concerned over the process used to apply changes, would like to
suggest a change to the process. Review committee should approve the diff
marks to the standard so that Farance can just apply the changes.  Page 1 of
N553 suggests a similar change to the process.

Walls, concerned that all items already added have had at least one
substantial problem, in response to this has produced a paper proposing an
improved approval process. (Document N556)

Discussion on process described in Document N556

Simonsen suggest that a review committee is established for each proposal
that is to be incorporated

Mooney, clarification of discussion, proposed process would mean:
Vote for content and vote for actual words.

Meyers, no substitute for seeing the final words that go into the standard,
suggest future proposals should have actual words and changes to the draft.

Simonsen suggest a standing document, listing the current status of all
changes to the standard.

MacDonald concerned over lack of clarity over convergence on documents via
email discussion, just don't know when reviewers are finished.

This issue will be finally resolved under item 8 on Tuesday.

4.   Document  N572 (X3 96-036) long long proposal (revision of N499)
Presentation  by Jutta Degener

Discussion about merits of  long long during porting between Keaton and
Degener

Degener observed that it was her proposal under discussion  and did not want
to entertain discussion about an earlier Farance proposal.

Meyers, in favor of some sort of standardization to reign in variation in
compilers, does concede that the proposal is ugly. Feather noted that the
preprocessor needs to be 64bit.

Plum, strong expression of C++ opinion against syntax of long long .  On the
preprocessor, should consider that  pp does its arithmetic in widest
supported type.

Keaton convinced that long long is wrong but in standardizing existing
practice would consider in voting for the proposal.

MacDonald is this the ideal way to solve the problem. Degener, no.

Farance disagrees with the fact that programmers do not want to know about
precision.

Plum, look at architecture of Java. World wants a world where every user
knows what size to expect.

Meyers,  When standardizing existing practice is this the best possible
solution does not apply. DEC compiler has both int64 and long long.  In the
real world there is a lot less elegance than we would like.

Jaeschke  considers the 64bit issues is a specific problem and not thinking
of using this solution to cope with 128 bits, MacDonald agrees.

Keaton paper will make good rationale material for long long discussion as
will France papers.

MacDonald requests additional rationale in the form of examples  on why we
chose the types of integer constants

FV Formal X3J11 Vote on N572 long long proposal
long long proposal

Moved Meyers seconded  Walls, that N572 (long long proposal) be passed
on to a final editorial review committee to draft the precise changes
to incorporate the proposal into the C9X draft.

5.   Extended Integers Paper N551 ...

Presentation by John Kwan on addition of integers of 128 bits to the
inttypes.h header file.

Discussion about the types involved and what promotion rules might apply.

Intense discussion about how inttypes.h will go into the standard. Should not
require types in inttypes.h to be built in types. Meyers, the term integral
types has been interpreted in a very narrow manner would like to see the term
expanded to included types in inttypes.h

Plauger, believes with a clean programming technique then it would be
possible for size_t and ptrdiff_t  to be a type from inttypes.h

Meyer,  OS's coming along that want 32bit ints but also have 64bit objects
e.g. addresses.

**** Meyers will work on a paper to allow integral promotion for
additional integral types, Kwan, Farance, Feather and Degener to assist.

Summary, wish to supply strtoimax and strtomax but not mandate their
existence.

Walls, reason for these functions is just convenience.

Plum, recognition that vendors will find the need for ever increasing integer
types during life of the standard.  Drafting committee, needed :

**** John Kwan will lead group, MacDonald Farance, Walls , Meyers

Straw vote to do we want to see INT128 issues again on agenda.

6.   Removal of Fast Types from inttypes.h Document N555
     Presentation by Douglas Walls:

Plum what would programmer use instead of int_fast16_  if it was
removed ?

Meyers suggested that fast types is similar to the optimization  flag it is
up to the vendor to do what they want and the user pay their money and take
their chance. It is as best a first level approximation of what is the
fastest type, similar to what is obtained by holding a gun to the compiler
writers head and insisting that  they confess which is the fastest type.

Prolonged  circular discussions on what to do with this issue

Keaton only feature that we have that allows the compiler to optimize on size
of type.  Discussion diverged into the use of the register keyword.

Fast functionality allows programmer to tell compiler it may make certain
assumptions, is a new optimization functionality. There is no other way to
tell the compiler it is allowed  to use certain types.

Plum inttypes.h is already in use and we should therefore be more
conservative in changing  the header.

FV X3J11 Formal Vote

Moved Walls seconded  MacDonald, that N555 (Removal of Fast Types from
inttypes.h) be passed on to a final editorial review committee to draft
the precise changes to incorporate the proposal into the C9X draft.

12.
Rationale

John Benito:

Currently adding MSE to document, need to add restricted pointers, rationale
is available for the following:

Designated initializers
Empty macro's
Restricted Pointers
MSE
Some feed back from Jaeschke

Don't have rationale for the following
inttypes.h
long long
VLA's
Compound Literals
signed integer division
// comments
tag compatibility

Will be in the post Toronto mailing

Review committee for the rationale, MacDonald, Tydeman, Farance, Jaeschke,
Benito

**** Benito to supply rationale for distribution prior to August 16

**** Committee to review latest version of rationale by August 30

**** Benito and Farance will work together to synchronize 
the rationale and the draft as best they can.

Farance not happy about merging print/scanf and wprintf/wscanf and will not
do so.

13.  VLA's

Issue 1:
....

int n;
struct tag{
     int n;
     int (*p)[n];   /* which n? */
     int a[n];      /* error    */
} int (*f)(int x[n]);

Propose that we remove pointer to VLA.  and make int (*p)[n]; illegal

SV, Straw Pole to make the above an error
F  O  U
5  7  7

Issue 2:
Declarators:
How many declarators ?
     int z[n++][n++];     /* behavior not fully specified */
     int (z[n++])[n++];
or
     int (z[n++])[n++]=1;
parenthesis gives us a sequence point in declarators but not expressions.
Behavior is clearly non portable, but it is not agreed what level of sin has
been committed. Unspecified ordering causes non portable behavior.

Plum proposes to delete sentence referring to sequence point and leave the
behavior unspecified. Meyers issues is to make the above wrong:

Irvine minutes pg 17 raised this issue:
C9X: 6.5.4 para 3
Concern that we have not got what we wanted

int n=5;
struct tag {
     int (*p)[n++];
} a[n++];

Proposed words:

Inside an init-declarator or parameter-declaration an object shall have its
stored value modified at most once by the evaluation of  an expression.
Furthermore, the prior value shall be accessed only to determine .....

int b[n++][n++],c[n++];                 /* These 3 lines will all */
void f(int x[n++][n++], int y[n++]);    /* become  undefined      */
int (*p)[n++] = & b[n--];

John Benito,

Plum, need to discuss how the 31 significant initial characters in an
internal identifier relates to extended identifiers.

Walls, desire to change the largest possible number assigned by the #line
directive.

Discuss each of the limits in turn.
63 nested levels. MacDonald thinks it should be bigger, suggest this should
be 127, no objection.

32 nested levels of conditional inclusion, MacDonald suggested larger,  63 no
objection

31 pointer, array, ......keep at current of 12 fits in 64bit

.. keep others until
2047 external identifiers in one translation unit, change to 4095.
2048 macro id in translation limit, change to 4095

65535 bytes in an object
15 nesting levels for #include
1023 case labels  for a switch
1023 members in a structure

17.  Electronic  Distribution Policy

Keaton and Keizer
Electronic distribution of minutes:

Stages in Production of Meeting Minutes.

Preliminary :
     Distributed to attendees at the meeting
Draft:
     Distributed to reflector
     mailing (also distributed through SC22)
Approved:
     (As amended at the next meeting).
     These are virtual and do not actually get distributed.

 minutes.

Approved minutes to be made available on the public web site.

Proposal
     Summary Minutes
     Details of discussion

Circular discussion regarding the degree of openness that should apply to the
minutes. Simonsen suggested that we should have both the current style of
minutes for distribution and additionally an executive summary for more
public consumption. Plum, reminder that X3  have encouraged a minimalist
approach to minute keeping.

Suggested wording as follows:

Copyright(c) 199X, ISO/IEC. This is an UNAPPROVED draft of C9X. Do not use or
claim conformance to this draft. Duplication permitted only for the purposes
of Standards formation.

Simonsen, suggested wording of where to send comments should be added.
Plauger confirmed any comments should be sent to their national body to
ISO/IEC, and any statement should convey this information.

Discussion about the word `use' as clearly people will want to use the
document.  Resolved should remain as this allows the document to be
frequently changed without come back.

19.  Floating Point N546, N547

Jim Thomas, suggested that their will be no preamble as this has happened
often enough before,  so don't get the idea that it is OK to doze off.

Removed overloading.
Discussion over infinity, NAN and need for compiler support.

     Normative (conditional)
     Line item consideration  issues solicited
     Suggested changes minor, mostly  from Tydeman and Thomas.

MacDonald concerned that recommended practice may favour some vendors over
others., this seems to go against the normal practice of equality to all.

Recommended Practice Issues:
Base document does not recommend IEEE practice.

The membership of JTC1/SC22/WG14 has been advised that many customer s of the
C programming language Standard
have had difficulty discovering and/or obtaining the Technical Corrigenda)
that have been made to the C Standard. WG14 requests that it be allowed to
make these and future TC's publicly available on the World Wide Web.

Like publicly available software patches when the software package is not
publicly available these documents contain only the changes and not the
entire Standard. Thus there should not be an issue with respect to
revenue....
We empower the Convenor to  request SC22 to allow publication of TC's on the
web.

23.  Complex Arithmetic Document N557

Presentation: Jim Thomas

Overloading has been removed from the paper
Plum, what is the compatibility situation between C and C++: Thomas, two
overlap to a  large degree. Plauger C++ silent on instantiation of template
complex with anything other than float, double or long double.
Discussion about how to program in the intersection of the two languages.
Believed if you write obvious code, then odds are high that code will look
the same. In C++ the maths functions are overloaded.

Plauger, group of Japanese to announce an embedded C++ subset at end of year.
Will include complex.

Discussion on wording in paper followed.......... Contain the use of the term
real floating type.......

Discussion , describe the complex in terms of a struct    {real; imaginary;}

24.  Boolean Support
Presentation Tom Plum

Meyers, keen that we nail things down more tightly,  does not want enums
(because want bool bit fields)
enums more useful for debuggers. Kwan echoing concern about use of bool as a
1 bit bitfield. MacDonald, current preference is for unsigned int. Plum,
better as plain int due to volume of practice, but happy with other
solutions. Keaton should say bitfields are zero and 1, but leave type
unspecified.

Conclusions, revisions as a package:
bool bitfield of size has to evaluate to 0 or 1
typedef enum {false, true}bool;
#define false 0
#define true  1
promotes to int or unsigned int
type of bool is unspecified but promotes to int or unsigned int

Discussion of merits of overloading in context of math library.
Plum, impression maths user want just to say  abs(x) an get overloading..
Plum, liaison point of view is that set of maths programs that are compilable
with C and C++ will be much greater if you can just use the same name.

MacDonald, have had a number of request for this.  Plauger, a
lightweight (good) version of overloading.

160, 166  Mooney


Meyers Defect Report 157
Is there any place where you need to use the real type rather than a typdef
for a type.

Answer is yes, yes, accept proposed response.

**** Meyers subgroup to supply final wording for DR 157

32.1 Defect Report 158
Adopt first suggested TC wording.
32.2 Defect Report 145
Under section 6.4 Constant expressions
proposed words for suggested Technical Corrigendum:

An address constant is a NULL pointer, or a pointer to an lvalue designating
an object of static storage duration, or to a function designator; it shall
be created explicitly, using the unary & operator or an integral constant
expression cast to pointer type, or implicitly, by the use of an expression
of array or function type.
....

Heated discussion, do agree that there is a problem as described in the DR.
Meyers suggested changing wording, Such a constant expression shall be or
evaluate to one of the following:

No objections, closed out.

*    *** Jones group to produce final wording for DR 145

Discussion about Future Change vs Technical Corrigendum
Keaton, we should not be modifying the old standard. Plauger it would be
preferable not to produce another TC prior to the new standard.

Resolved everything into future changes. Suggested call them suggested Future
Correction.

*    *** Dave Mooney will act a focal point to ensure that all RR/TC/Future
 Change wording makes it the Convenor within a the next 4 weeks.

Proposed to have two lots of wordings, Future changes and Future Correction.

*    *** Feather and Mooney will produce new boiler plate for DR's.

32.3 DR 151
Revisit of the response to this DR.

Walls' argued the point that the response was incorrect but after a prolonged
discussion. It was accepted that Walls' position was valid however C had
standardized existing practice and hence the behaviour was deliberately
inconsistent.

32.4 DR 159

Agree with suggestions but need final words.
*    *** Mooney subgroup will supply the appropriate words

32.5 DR 160

In 7.1.3 Reserved Identifiers, change bullet

All identifiers that begin with an underscore are always reserved for use as
macros and as identifiers with file scope in both the ordinary identifier and
tag name spaces

Change bullet 5 to:

Each identifier with file scope listed in any of the following
subclause(including the future library direction) is reserved for use as a
macro and as an identifier with file scope in the same name space if any of
its associated headers are included.

*** Mooney to prepare suitable words and deliver to the Convenor.
32.6 DR 161
*    No change required, some rationale will be added. Jones
32.7 DR 162

Except for the strftime function, these functions each return a pointer to
one of the two types of static object; A broken down time structure or an
array or char. Execution of any of the functions that return a pointer to one
of these types of object......

34.  LIA
Discussion on LIA
Mr  Willem Wakker - Convenor of WG11 gave a short overview of the work items
of WG11 on language independent arithmetic.

LIA-1 Integer and floating point arithmetic.
LIA-2 Elementary numerical functions.
LIA-3 Complex arithmetic and functions.

Next version of LIA-w currently with editor, hopefully will have document by
end of August for a second CD ballot.

CD ballot - September or October.

*    *** Meyers to contact WG11 project editor and obtain the latest copy of
 LIA-2 in time for the September mailing.

LIA-1 requires signaling NAN's if you support IEEE maths (which is now
conditionally normative) (this has been described as a substantive effort to
support)

Plum, Asked about bounded integer arithmetic, if it was required.
LIA-2 will also create substantive work in C standardization for support.
LIA-3 will start when LIA-2 is stable.

LID, (Language Independent Data Types)

Farance, comments supplied. LID has only one integer type but can produce new
types with specified ranges. Consider that requirements for a binding for LID
is not very clear, looks like only one type of integer.

Kwan, LIA is to help porting of algorithm from language to language.
LIA project tries to specify the operations on certain data types and the
results obtained.

The datatypes are for specifying interfaces in language independent
datatypes.
Jaeschke, What is impact of LID on WG14 ?
LID looks like a small amount of effort.

*    *** Farance, will work with Tydeman and Thomas on LIA binding.
*    Farance will produce a paper on LID as it relates to C
*    *** Tydeman will liaise with WG11 on LIA-2
Need a user mechanism for creating a signaling NAN

36.  Use of Restrict in Standard Libraries (Document N566)
MacDonald:
Tried to go through standard and find all the places where objects overlap

Martin raised issues of breaking the standard library that C++ pointed to.
Plum, C++ points to ISO 9899:1990.   Feather, POSIX has the same problem.
Plauger, not a problem that we can solve.

Thomas, makes sense for things like memcpy(), but seems to complicate the
interface.

MacDonald:
The library is currently broken whenever objects overlap.
Discussion about user beware vs user understanding what is going in the
restrict paper. Prolonged discussion over impact on I/O related functions.
Plum, Consider pairing list down to just the places where there is a  source
and target. MacDonald, yes no problem.

Mooney proposed adding (but not limited to).
Does not state whether you have to support bool bitfields.

/* Problem with the following idiom */
bool x;
y = x * expr;

if bool is an unsigned value and expr is a signed negative value then result is an
unsigned expression, an hence it is implementation defined.

41.9 upper and lower operators N564
Farance, overall not in favor of proposal
Meyers, likes the abstract but thinks paper needs a lot of work
Kwan, finds the terminology very confusing, supported by Simonsen suggests
top and bottom.

Degener, this proposal does not seem to be in the spirit of C language.
Meyers, would like quite like to be able to supply information that the
compiler knows about.

Plum, C++ library component numeric limits, raises some compatibility issues
if C9X goes down this path.

Even in C++ if you create a new arithmetic type then you still have to do the
work to supply the numeric limits.

Farance willing to contact author an explain LIA issues.
MacDonald tentative yes to acting as a champion for this proposal.
Meyers would like some sort of type probe mechanism.

MacDonald may make limits.h obsolete.

Plum, presented foil showing a possible quick and dirty macro solution:

numeric_limit(T, feature)

is_specialized
min,max, is_signed, is_integer, is_exact, radix, epsilon, round_error
min_exponent, max_exponent

Feather, Farance interested in working on this sort of a proposal

Meyers, would favour compiler built in as macros may pollute name space.

Empower the redactor to include
Keaton requested that we create a high water mark i.e. wait until all DR up to
a certain point (DR175) are completed before we include them into the draft.

Resolution:
Accept Document N559 working draft 6 with appropriate corrections as our
working document.

Simonsen, proposes that all action items and resolutions are in printed form
prior
to voting on final day of meeting. Not  a supported position.
Thanks to Ed Keizer and the University.
44.  Bool Revisited
Walls, concerned about issues as is Mooney.
No objection to agenda time for next meeting.
45.  N580/581 varargs macros
Feather presented slide:
#define printf(f, ...) \
     fprintf(stderr, f, __VA_ARGS__)

printf("%s %d", str, I);
fprintf(stderr, "%s %d", str, I);

printf("No values") Not allowed
But
#define printf(...) fprintf(stderr, __VAR_ARGS__)
then allow format but no other arguments.

Recycled back into the document queue
46.  sizeof wrapping N582/583
Feather suggests that it is possible to have objects to large to be
represented by
size_t
Farance, debate should continue on reflector

47.  Editorial Issues
Suggested that an editorial group is formed to focus on editorial type
issues.
Benito, Walls, Keaton, Farance
Farance to form editorial committee, consider meeting the Sunday of Toronto

                                Unapproved Draft June 1996 US TAG Minutes


    1  US TAG Meeting

        Jaeschke convened the meeting of the US TAG at 4:58 pm on 27 June
        1996.  Meyers served as secretary.

        Jaeschke stated that the US delegation had already been approved
        at the last meeting; no further votes were needed.

        Farance requested that he be approved as the X3J11 Liaison to the
        Representative to the X3 Information Infrastructure Standards
        Panel (IISP).

        Plum asked that Farance not represent a position for X3J11 until
        X3J11 has voted on an issue.

        Farance stated that he would handle this similarly to his reviews
        of other standards.  He would propose a position on the reflector
        to see if there was any disagreement before representing a
        position.

    FVP (Farance/Keaton) Move that Farance be X3J11 Liaison to the
        Representative to the X3 Information Infrastructure Standards
        Panel.

        Tydeman stated that LIA-1 incorrectly defines floating-point
        division by zero.  LIA-1 treats 0./0. and 1./0. the same:
        undefined.  LIA-1 should treat the division of any non-zero
        finite floating point number by zero as the pole exception in
        order to be better aligned with LIA-2 and IEEE floating point.
        Tydeman asked, since LIA-1 has been approved as an ISO Standard,
        how do we get it changed?

        Plauger stated that X3J11 should request that X3 pass on a defect
        report.  Plauger can also communicate though SC22.

        Meyers stated that he could not take a position on this question
        without seeing a write-up.

        Plum suggested that Tydeman discuss the issue on the mail
        reflector.  X3T2 is the US Tag for LIA.

    *** Tydeman will provide additional information on the floating point
        divide by zero problem in LIA-1 in a paper or on the email
        reflector.

        Keaton announced that the password to the private FTP site has
        changed (the policy is to change the password every meeting).
        The password is available from heads of delegations.

        The meeting adjourned at approximately 5:20 pm on 27 June 1996.
