From 306bd3a2bf59423938f71279b4208fdf0114df24 Mon Sep 17 00:00:00 2001
From: Raja R Harinath <harinath@src.gnome.org>
Date: Mon, 9 Oct 2000 21:06:01 +0000
Subject: Work with beta autoconf 2.50. * configure.in (GLIB_MAJOR_VERSION):
 Use GLIB_DIVERT_BEFORE_HELP instead of AC_DIVERT_PUSH(),AC_DIVERT_POP.
 (AC_CHECK_HEADERS): Remove redundant AC_DEFINE(HAVE_...). (REALLOC_0_WORKS):
 Move AC_DEFINE outside AC_CACHE_VAL. (dlopen): Quote nested AC_CHECK_...
 calls.

* acglib.m4 (GLIB_TR_SH, GLIB_TR_CPP): Utility macros copied from
beta autoconf 2.50.
(GLIB_DIVERT_BEFORE_HELP): New macro that works both with autoconf
2.13 and beta autoconf 2.50.
(GLIB_SIZEOF, GLIB_BYTECONTENTS): Use GLIB_TR_*.
