The good news is that TR 18037 - Extensions for the Programming Language C to support embedded processors - is approved for publication; during the final JTC1 ballot only one No vote was issued (from Switzerland, to a large extend the same vote as during the previous ballot). The bad news is that John Benito discovered the first genuine Embedded-C defect. The source of this defect is as follows: we have suffixes for the various fixed-point types and use these suffixes also to identify the return type of various functions. The suffix for the accum type used to be the letter 'q', but this was changed (based on comment UK-3, discussed and decided on in Santa Cruz, see n990) to 'k'. This implied that the name of the function to convert a string to an accum value 'strtoq' was changed to 'strtok', and we did not noticed that this clashes with the string.h function of the same name (see 7.21.5.8). Solutions? Don't know yet. Possible options: - leave as is; this would imply that string.h and stdfix.h cannot be used simultaneously. - change the 'k' back to 'q'; a rather big change but, if done quickly, would not hurt too many implementations ... - invent a new name for this specific case ('strtokk'?): not nice but simple to do. My favourite is to remove 7.21.5.8 from the standard (who would use this anyway?) but I don't think that this is a real option. Suggestions? The quicker we react, the less damage is done ... - Willem. aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa Willem Wakker email: cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc ACE Consulting bv tel: +31 20 6646416 van Eeghenstraat 100 fax: +31 20 6750389 1071 GL Amsterdam, The Netherlands www: http://www.ace.nl eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
