* [Bug libc/4364] New: _XOPEN_VERSION and unistd.h @ 2007-04-14 23:44 madcoder at debian dot org 2007-04-14 23:45 ` [Bug libc/4364] " madcoder at debian dot org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: madcoder at debian dot org @ 2007-04-14 23:44 UTC (permalink / raw) To: glibc-bugs quoting from: http://bugs.debian.org/203412, attached is a patch =================================================================== SUSv3 [0] states that: The following symbolic constant shall be defined only if the implementation supports the XSI option; see XSI Conformance. _XOPEN_VERSION [XSI] Integer value indicating version of the X/Open Portability Guide to which the implementation conforms. The value shall be 600. It furthermore states [0]: _XOPEN_UNIX [XSI] The implementation supports the XSI extension. Therefore, if _XOPEN_UNIX is defined, as it is, unconditionally to 1, then at least at some time _XOPEN_VERSION must be defined to 600. The only place I can find that _XOPEN_VERSION is mentioned is unistd.h, which has the following snippet of code: /* X/Open version number to which the library conforms. It is selectable. */ #ifdef __USE_UNIX98 # define _XOPEN_VERSION 500 #else # define _XOPEN_VERSION 4 #endif There is a complicated set of preprocessor directives in features.h that chooses appropriately; for _XOPEN_SOURCE=600, _XOPEN_VERSION=500, not 600.
