Well, after revert the changes all works fine. So definitely is
something wrong in my changes. But since I don't have experience with
autogen, configure scripts, ... I can't see where is the problem. First
I define _NATIVE_OBJC_EXCEPTIONS, according with the value saved in
GSConfig.h. This is necessary, in other way we can't compile gnustep
headers. Second I keep the gnustep flags in CFLAGS and CPPFLAGS, because
these are necessary when execute make. If gnustep is installed using the
fsh layout I suppose this isn't necessary. But if is installed with
gnustep layout, we need these flags. With these changes I can configure
emacs (with gnustep) successfully. But of course there is something
wrong. These are my changes.

What is wrong? Thanks.
