   (Thanks for finding this, Andrew.)

   Is there any reason you're not testing processing_gcc_compilation,
   instead of checking the last N_FUN's desc?

Other than that it's a global variable?  No not really.  I suppose it
was because the patch actually is a slimmed down version of a patch
that tried (and failed) to distinguish between a broken GCC and a
fixed GCC too.

Do you prefer checking processing_gcc_compilation?  I suppose it's
better because it makes the intent clearer.
