Thank you.  A -O0 -g3 build succeeds now but a -O3 build currently
fails thusly:

In file included from ../../src/emacs.c:68:0:
../../src/bignum.h:25:17: fatal error: gmp.h: No such file or directory
  #include <gmp.h>
                  ^
compilation terminated.
make[1]: *** [emacs.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory `/c/emacs-git/trunk/opt/src'
make: *** [src] Error 2

My -O0 builds have, for historically reasons, also

-Wno-logical-op --Wno-missing-braces

and

--enable-checking=yes --enable-gcc-warnings=warn-only --enable-check-lisp-object-type=warn-only

but I doubt that these can be relevant.  Any clues?  A couple of
warnings from the -O0 build just in case they could hint at anything.
