This -.su file is created by genassym which calls GCC using stdin for
the input file.  The attached patch feels a bit hackish, but works for
me.  Any reason not to commit it now, or does anyone have a cleaner
fix?  I certainly didn't want to add all the ugliness of checking if the
current compiler is GCC and !vax !

Cheers,
Simon.
