From 06e2c646693d5310011c0190509682a23097b8ae Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 15 Oct 2015 19:31:46 +0000 Subject: [PATCH] Remove stddef.h configure test. There is a configure test "for libc-friendly stddef.h", which sets a makefile variable stddef.h that appears to be nowhere used. It appears the uses of this variable were removed by: Tue Feb 21 00:10:50 1995 Roland McGrath * Makefile (headers): Remove $(stddef.h). * Makeconfig (stddef.h): Variable removed; now require gcc version >= 2.2. * stddef.h: File removed. (having been added by Wed May 26 14:44:19 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu) * configure.in (autoconf checks): Add new check for a libc-friendly stddef.h. so the test was of use for less than two years, before being obsolete for over 20 years). This patch removes the test. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_friendly_stddef): Remove configure test. * configure: Regenerated. --- ChangeLog | 5 +++++ configure | 38 -------------------------------------- configure.ac | 18 ------------------ 3 files changed, 5 insertions(+), 56 deletions(-) diff --git a/ChangeLog b/ChangeLog index b759929bf9..bcf53f9b7f 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2015-10-15 Joseph Myers + + * configure.ac (libc_cv_friendly_stddef): Remove configure test. + * configure: Regenerated. + 2015-10-15 Florian Weimer * stdio-common/vfscanf.c (MEMCPY): Remove macro. diff --git a/configure b/configure index f0cd17580c..4b96ec7ad7 100755 --- a/configure +++ b/configure @@ -5524,44 +5524,6 @@ if test $ac_verc_fail = yes; then fi -{ $as_echo "$as_me:${as_lineno-$LINENO}: checking for libc-friendly stddef.h" >&5 -$as_echo_n "checking for libc-friendly stddef.h...
