sync'd ./config with gcc

[DJ Delorie <dj at redhat dot com>]

The toplevel config/ is now the same between gcc and src.

I've merged all the src-only patches from ./Makefile.in and
./configure.in to gcc also, I'll be working on applying the gcc-only
patches to src next, which should make ./Makefile.in and ./configure*
identical also.

2001-10-07  Joseph S. Myers  <jsm28@cam.ac.uk>

	* acinclude.m4: Fix spelling error of "separate" as "seperate".

2001-05-22  Jason Merrill  <jason_merrill@redhat.com>

	* mt-linux (CXXFLAGS_FOR_TARGET): Lose -fvtable-thunks.

2001-01-27  Richard Henderson  <rth@redhat.com>

	* mt-alphaieee: New file.

2001-01-02  Laurynas Biveinis  <lauras@softhome.net>

	* mh-djgpp: do not set CFLAGS.

2000-08-04  Mark Elbrecht  <snowball3@bigfoot.com>
