I would think so, yes. I also suspect, as have been suggested to me by

relevant also for this.

Sure, this is from my current ongoing test of gcc-3.1 (Sun Apr 7

Sorry, you'll perhaps have to help me a bit more here.

Here's what I do (the unix run, not -fPIC or -fpic):

Sure, this is what I got. See also 

http://gcc.gnu.org/ml/gcc-bugs/2002-04/msg00401.html

or around that thread as I suspect they might be related :-)

No problem, my fun.
