Subject: Fix missing timespec definition for sys/stat.h (BZ #21371)
X-Git-Tag: glibc-2.26~588
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d76d3703551a362b472c866b5b6089f66f8daa8e;p=thirdparty%2Fglibc.git

Fix missing timespec definition for sys/stat.h (BZ #21371)

As indicated by the bug report, the 'struct timespec' definition
is not defined for '_XOPEN_SOURCE=700' and '_POSIX_C_SOURCE=200112L'.

It is because current code only includes its definition if __USE_ATFILE
is defined and the define is only set with:

  1. _GNU_SOURCE and/or _ATFILE_SOURCE definition.
  2. _POSIX_C_SOURCE >= 200809L

However, the 'st_*' fields in 'struct stat' are defined if __USE_XOPEN2K8.
This patch uses the same logic for 'struct timespec' inclusion.

Tested on x86_64-linux-gnu.

	* io/sys/stat.h: Use __USE_XOPEN2K8 insteaf of __USE_ATFILE for
	struct timespec definition.
