Thank you, Mark. It worked. Whenever you have a chance (either before
the 1.2.7 release, or after it), you may safely remove EXTRA_CFLAGS,
and all the references to it, from win32/Makefile.gcc.

BTW, I think that win32/Makefile.emx can go to old/win32/Makefile.emx.
I looked for the emx/rsxnt layer, it hasn't been updated in more than
10 years, and I found no uses of it, other than references to antique
OS/2 sites.

Sincerely,
Cosmin
