Update.
1998-06-26 14:37  Ulrich Drepper  <drepper@cygnus.com>

	* configure.in: Check for -fexceptions.
	* config.make.in: Define exceptions, not no-exceptions.
	* misc/sys/cdefs.h: Define __PMS.  When using modern g++ define
	__P to use throw().
	* misc/Makefile: Define CFLAGS-tsearch.c and CFLAGS-lsearch.c to
	$(exceptions).
	* stdlib/Makefile: Likewise for bsearch.c, msort.c, and qsort.c.
	* misc/search.h: Use __PMS in tsearch, tfind, tdelete, twalk, tdestroy,
	lfind, and lsearch prototpypes.
	* stdlib/stdlib.h: Likewise for bsearch and qsort.

1998-06-26  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/fpu/bits/mathinline.h (__finite): Use C code, not asm.

1998-06-25  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makefile (remove-old-headers): Make phony.

	* configure.in: Substitute @old_glibc_headers@.

1998-06-26  Ulrich Drepper  <drepper@cygnus.com>

	* libc.map: Remove __libc_uid.

1998-06-24  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* manual/terminal.texi (Allocation, Pseudo-Terminal Pairs): Fix
	typos.

1998-06-26  Ulrich Drepper  <drepper@cygnus.com>

	* libc.map: Add Alpha-specific io function from protected namespace.
