THe first thing I would recommend doing is finding what what version of gas
is being used by the compiler:

/home/marcof/gnu/lib/gcc-lib/hppa1.1-hp-hpux10.20/2.97/../../../../hppa1.1-hp-h
pux10.20/bin/as -v

Ought to give you that tidbit.

Then I would do an nm on your libgcc.a

Also, did you configure with --enable-shared?

My best guess is you're running into some kind of weak symbol problem.
