Eric took an action to update the proposal to resolve the overlaps appropriately. +Bug 0000615: pthread_setcancelstate should be async-signal-safe OPEN http://austingroupbugs.net/view.php?id=615 We now have reports on AIX and Apple.

Bug 0000721: Internal storage vs static storage OPEN http://austingroupbugs.net/view.php?id=721 This item is still open. Bug 0000375: Extend test/[...] conditionals: ==, <, >, -nt, -ot, -ef OPEN http://austingroupbugs.net/view.php?id=375 This is still left open due to discussions pending on the reflector.

Martin has also forwarded this to The Open Group Base Working group for their consideration. * Current Business Eric has an action on fnmatch() with FNM_PATHNAME whichis still open. Bug #811: precondition for mutex destruction unclear; example contradicts normative text OPEN http://www.austingroupbugs.net/view.php?id=811 Action: Andrew to contact Dave Butenhof for his input on this item. This has been completed, and a response was received after the meeting. It should be discussed on the next teleconference. Bug #814: unclear behavior when 'size' keyword deleted or overriden Accepted as Marked http://www.austingroupbugs.net/view.php?id=814 This item is tagged for TC2-2008 An interpretation is required. Interpretation response: The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: If a user overrides data needed to determine where a file is in an archive, the results are undefined. Notes to the Editor (not part of this interpretation): Add after P3038, L100931: If the -o delete=pattern, -o keyword=value, or -o keyword:=value options are used to override or remove any extended header data needed to find files in an archive (e.g., -o delete=size for a file whose size cannot be represented in a ustar header or -o size=100 for a file whose size is not 100 bytes), the behavior is undefined. Bug #815: sigwaitinfo() equivalence to sigwait() needs additional exception Accepted http://www.austingroupbugs.net/view.php?id=815 This item is tagged for TC2-2008 Bug #816: does fflush(NULL) affect seekable read streams? Accepted http://www.austingroupbugs.net/view.php?id=816 This item is tagged for TC2-2008 Bug #817: O_SEARCH condition for *at() functions worded incorrectly Accepted http://www.austingroupbugs.net/view.php?id=817 This item is tagged for TC2-2008 Bug #818: fmemopen should allow 0-size buffer Accepted ad Marked http://www.austingroupbugs.net/view.php?id=818 This item is tagged with C11 and TC2-2008 Delete line 29196. Add a new paragraph after 29200: [EINVAL] The size argument specifies a buffer size of zero and the implementation does not support this. Add to Future Directions after line 29235 A future revision of this standard may require support of zero length buffer streams explicitly. Bug #820: missing underscore in _POSIX2_VERSION description Accepted http://www.austingroupbugs.net/view.php?id=820 This was a mistake in the application of changes from TC1. Therefore, this can't be marked as a TC2 bug, but needs to be fixed in the current documents before TC2 is produced. AI Andrew: define and apply a new tag for this bug (for errata).
