Clamage called the meeting to order at 08:50 (GMT+10) on Monday, October 1, 2007
Plum described the arrangements and facilities for the meeting.
Clamage had the attendees introduce themselves.
Clamage reviewed the patent disclosure rules.
Nelson reviewed membership rules. Nelson then circulated the attendance list and membership list. Clamage reviewed voting rules and reviewed procedures for the meeting.
Clamage presented the agenda (document J16/07-0235 = WG21/N2375).
Motion to approve the agenda:
Each of the Working Group chairs presented their plans for the coming week.
Adamczyk reported that there are about 20 papers due to be processed by the CWG. Due to the volume of papers to be reviewed, the CWG will have little time to address the CWG issues list.
Hinnant reported that the LWG has several new papers (about a dozen) to review. In addition, the LWG has a large number of open issues. Hinnant indicated that he expect the LWG to meet in a joint session with the concurrency group.
Stroustrup reported that the bulk of the work remaining to EWG is in concurrency, which is deferred to Boehm's subgroup. Lambdas are the other remaining open item for EWG, and that discussion will be deferred until Jaarvi arrives on Wednesday.
Crowl asked whether there was any intention to discuss proposals related to dynamic libraries. Stroustrup indicated that a discussion of dynamic libraries could also take place Wednesday.
Austern inquired about the status of proposals to introduce Garbage Collection (GC) to the language. Stroustrup replied that Spertus and Boehm are progressing well on an implementation of the GC proposal, but it is not yet ready, so they have requested that GC not be discussed at this meeting.
Motion to approve the minutes (document J16/06-0215 = WG21/N2355)
Sutter reported that five countries are represented at this meeting; all five have voting status.
Sutter also reported that a ballot on a New Work Item Proposal for an International Standard on special math functions for C++ has passed. However, some National Bodies voted no on this ballot, because they didn't want to see a separate C++ standard, even if WG21 is working on it.
There hasn't been a WG14 meeting since WG21 last met.
Stoughton reported that a study group meeting on a C++ binding to POSIX was held prior to the July 2007 meeting in Toronto. IEEE has voted to pursue this effort.
As well, Stoughton reported that POSIX is in a Final CD ballot which finishes November 2nd.
Plum reminded the committee that OWGV is a quasi-temporary group whose mandate must be re-approved every year. He then explained that OWGV was meeting concurrently with the present WG21/J16 meeting at the same location, and encouraged WG21/J16 members to find time to sit in on their discussions.
The current draft of the WP is J16/07-0229 = WG21/N2369.
Motion to accept the working paper
Sutter reviewed two possible schedules for completion of the C++0X standard. These are identified as Strawman Option X and Strawman Option Y in J16/07=0277 = WG21/N2417: "Timing Options for Kona Discussion"
Much discussion ensued.
We have three subgroups: Core, Library, and Evolution. There will be a subgroup of Evolution to deal with issues relating to concurrency.
The committee broke into subgroups at 10:30 (GMT+10).
See 10.1, below.
WG21 resolves that for this revision of the C++ standard (aka "C++0x") the scope of the memory management extensions shall be constrained as follows:
