Ended up finding one of your mails in the archives describing the 
atoll() issue: <http://gcc.gnu.org/ml/gcc-bugs/2003-06/msg02965.html>.
Added a definition to the gcc "fixed" headers from 2.95.2. After
fixing that, it left me with a bad header after the gcc fix headers
step. Some hand tweaking there, and I seem to have a working compiler.

If anyone's interested, I'll work out what I needed to do, and pass it
on.

BTW: I wasn't using bash.

Thanks for the reply,

I love deadlines. I like the whooshing sound they make as they fly by.
