OK, now that I have what looks like a working package with gcc 3.3.3, I

 But that per se shouldn't be an issue, I don't think.

So, how can I help you?  Use gdb in some fashion?  The binary is, of course,

We need to know what is the problem, so building with debugging turned
on is needed.  Also try different grades of optimization, what do you
use now, e.g. -O3?  Does it work with -O2 then, and so on.  There are
several bugs in the optimizer, i.e. the unit-at-a-time stuff is breaking
a lot of code, however this is not a bug, this is by design;)
If it is a problem with the optimizer we will figure out which flag
breaks the binary and report a bug.
