From fef1696ffcfaeb438ebd8c519edd3baf212b76e7 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Wed, 21 Aug 1996 01:02:53 +0000 Subject: [PATCH] * aclocal.m4: Include ../bfd/aclocal.m4. * configure.in: Add stdlib.h to AC_CHECK_HEADERS. Call BFD_NEED_DECLARATION on malloc, realloc, and free. * acconfig.h: Add NEED_DECLARATION_MALLOC, NEED_DECLARATION_REALLOC, and NEED_DECLARATION_FREE. * configure, config.in: Rebuild. * defs.h: Include and based on HAVE_*_H rather than __STDC__. Only declare malloc, realloc, and free if NEED_DECLARATION_* is defined. --- gdb/ChangeLog | 12 +++++ gdb/acconfig.h | 10 ++++ gdb/aclocal.m4 | 2 + gdb/config.in | 15 ++++++ gdb/configure | 152 +++++++++++++++++++++++++++++++++++++++++++++++++++++-- gdb/configure.in | 6 ++- 6 files changed, 191 insertions(+), 6 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index ce80109..12c9c28 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,15 @@ +Tue Aug 20 17:59:42 1996 Ian Lance Taylor + + * aclocal.m4: Include ../bfd/aclocal.m4. + * configure.in: Add stdlib.h to AC_CHECK_HEADERS.
