From: DJ Delorie Date: Wed, 29 Nov 2000 19:17:37 +0000 (+0000) Subject: * aclocal.m4 (LIB_AC_PROG_CC): Moved here from configure.in. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2ea7befd8e4c7e771401059d57452834b6a30da8;p=binutils-gdb.git * aclocal.m4 (LIB_AC_PROG_CC): Moved here from configure.in. (AC_DEFINE_NOAUTOHEADER): New - work around bug in autoheader. * configure.in: Call AC_C_INLINE and AC_C_CONST. Use three argument form of AC_DEFINE in dummy definitions block. Use AC_DEFINE_NOAUTOHEADER for real definitions of things defined in dummy block. Preload cache variables instead of bypassing tests, where possible. * acconfig.h: Removed. * xmalloc.c (xmalloc_failed): New function, does error reporting on failed allocation. (xmalloc, xcalloc, xrealloc): Use it. --- diff --git a/libiberty/ChangeLog b/libiberty/ChangeLog index 3a735f52b17..1428d4d36af 100644 --- a/libiberty/ChangeLog +++ b/libiberty/ChangeLog @@ -1,3 +1,17 @@ +2000-11-29 Zack Weinberg + + * aclocal.m4 (LIB_AC_PROG_CC): Moved here from configure.in. + (AC_DEFINE_NOAUTOHEADER): New - work around bug in autoheader. + * configure.in: Call AC_C_INLINE and AC_C_CONST.
