Decided to solicit input from FS developers. Eric to go to Linux, David to AIX and Jim to Solaris. Jim has completed his action (see bugnote 1691). Andrew should chase HP and Apple for input. +Bug 0000663: Specification of str[n]casecmp is ambiguous reopened http://austingroupbugs.net/view.php?id=663 Action on David to follow up with the IBM developers about the EBCDIC collation sequence.

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. Bug 0000789: Add set -o pipefail OPEN http://austingroupbugs.net/view.php?id=789 * Current Business Bug #847: open(O_CREAT), directories, and EISDIR Accepted as Marked http://www.austingroupbugs.net/view.php?id=847 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: The standard does not specify the behavior when open() is called with O_CREAT|O_RDONLY (or O_CREAT|O_SEARCH) on an existing directory. Additionally, some systems want to allow creation of directories using the open() function. This should be an allowed, but not required, extension. Notes to the Editor (not part of this interpretation): On page 238 line 7885 change: O_DIRECTORY Fail if not a directory. to: O_DIRECTORY Fail if file is a non-directory file. On page 1391 at line 45975 (open() description, O_CREAT), change: Otherwise, the file shall be created to: Otherwise, if O_DIRECTORY is not set the file shall be created as a regular file On page 1393 after line 46051 (open() description), insert a new paragraph: If O_CREAT and O_DIRECTORY are set and the requested access mode is neither O_WRONLY nor O_RDWR, the result is unspecified. On page 1394 at line 46098 (open() errors, EISDIR), change: The named file is a directory and oflag includes O_WRONLY or O_RDWR. to: The named file is a directory and oflag includes O_WRONLY or O_RDWR, or includes O_CREAT without O_DIRECTORY. Bug #848: make defaults CFLAGS to -O, but c99 requires a level Accepted as Marked http://www.austingroupbugs.net/view.php?id=848 This item is tagged for TC2-2008 An interpretation is required. Interpretation response: The standard states that by default make shall achieve results that are the same as CFLAGS=-O, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: The specification for the c99 utility does not support -O without an option-argument. In addition, if a subsequent argument is provided, the argument will be (erroneously) interpreted as an optimization level. Notes to the Editor (not part of this interpretation): On page 2945 line 97465 change: CFLAGS=-O to: CFLAGS=-O 1 On page 2949 line 97621 change: c99 −c −O $*.c to: c99 −c −O 1 $*.c On page 2949 line 97624 change: c99 −c −O $< to: c99 −c −O 1 $< Bug #849: Normative and informative text on return value of pthread_create() are incompatible Accepted as Marked http://www.austingroupbugs.net/view.php?id=849 This item is tagged for TC2-2008. On Page: 1602 Line: 51480 Section: pthread_create() In the APPLICATION USAGE section, change from: through the return value of the pthread_create() function to: through the thread argument of the pthread_create() function Bug #850: Standardize MAP_ANON OPEN http://www.austingroupbugs.net/view.php?id=850 This was discussed during the call and a proposed response has been added to the bug report, as bugnote 2281. This will be continued on the next call. Next Steps ---------- There will be no call on July 3rd. The next call is on July 10, 2014 (a Thursday) Calls are anchored on US time.
