	* malloc/malloc.h: Properly handle future GCC versions.

1999-05-27  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/configure.in: Change version checks to
	use AC_EGREP_CPP.  Change sed pattern to not use alternation.  Fix
	text of error message.

	* aclocal.m4 (GLIBC_PROVIDES): Define AC_LANG to `C'.
