Revision 135878 is OK. Has anyone else seen it? The Fortran CPP patch

http://gcc.gnu.org/ml/gcc-patches/2008-05/msg01267.html

may be the cause.

No idea how this can be related, but I already confirmed that r135881 is not
the cause. Working on it.

------- Comment #2 from hjl dot tools at gmail dot com  2008-05-26 06:58 -------
Revision 135882 is the cause. A simple testcase:

[hjl@gnu-26 gcc]$ cat x.cc
int
main ()
{
#ifndef __GNUG__
#error "This is bad."
#endif
  return 0;
}
[hjl@gnu-26 gcc]$ gcc -c x.cc
[hjl@gnu-26 gcc]$ ./xgcc -B./ -c x.cc
x.cc:5:2: error: #error "This is bad."

Accidently removed the conditional definition of __GNUG__. 
This seems to fix it:

Can you double what else you may have removed by accident? Thanks.

Did. Nothing else. Function define__GNUC__ defined 4 macros, my initial patch
only 3 :(

Ok to commit?
