I am sorry, let me clarify.

When you wrote, that you checked in patch for gcc-3.2 I just checked out
and it did not compile. Thus I assumed that you forgot to checkin
the new version of gc. I thought that you send the patch just for my
convinience, while CVS already contains the correct version of gc.

They do not break anything, so it's ok.

Sure.

I assumed that 'gcc-3.2' patch means all modifications that will make
testsuite work with gcc-3.2 . Now I see what you meant.

I think this is precisely the problem that calls for separation of
Frontend library. Your patch is a patch for a Frontend and it does
not apply to the testsuite, which tests the whole thing.

No. To make CVS spit e-mails to this mailing list we have to setup a
script in CVSROOT module of CVS. It is all described in SF SiteDocs.
This should take 45mins. including reading the docs. If you can get
it off my TODO list, that would be great.

Best regards
