Good news, http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37072 does
not actually seem to apply to upstream GCC since the change apparently
was a local one introduced by obrien in 2000.

The thing that puzzles me is why the documentation would state other-
wise, but I tracked this down to a commit in March 2002 and will check
with the original author


That said, if any of you introduce any changes to the system compiler
or are aware of any that have not been addressed upstream yet, please
advise and I'll see what can be done.
