From eb64b6d4571caea5fe39f6427565f849b09c23b6 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 8 Apr 2016 22:52:51 +0000 Subject: Fix limits.h NL_NMAX namespace (bug 19929). bits/xopen_lim.h (included by limits.h if __USE_XOPEN) defines NL_NMAX, but this constant was removed in the 2008 edition of POSIX so should not be defined in that case. This patch duly disables that define for __USE_XOPEN2K8. It remains enabled for __USE_GNU to avoid affecting sysconf (_SC_NL_NMAX), the implementation of which uses "#ifdef NL_NMAX". Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #19929] * include/bits/xopen_lim.h (NL_NMAX): Do not define if [__USE_XOPEN2K8 && !__USE_GNU]. * conform/Makefile (test-xfail-XOPEN2K8/limits.h/conform): Remove variable. --- include/bits/xopen_lim.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/bits/xopen_lim.h') diff --git a/include/bits/xopen_lim.h b/include/bits/xopen_lim.h index 26b4fba..7515ddd 100644 --- a/include/bits/xopen_lim.h +++ b/include/bits/xopen_lim.h @@ -77,7 +77,9 @@ /* Maximum number of bytes in N-to-1 collation mapping.
