In the ./configure step, did it or did it not detect support for
reliable floating-point exceptions?
HiPE requires reliable f.p. exceptions on Linux/x86. If they aren't
available, a linkage error like the one you showed will occur.
What does `uname -s` and `uname -m` say in your UML environment?
If your UML environment doesn't provide reliable f.p. exceptions,
then you should use ./configure --disable-hipe.
On an unrelated note: gcc-3.0 is known to have bugs related to it
generating code that touches stack slots _below_ the stack pointer.
Please switch to a saner compiler, like 3.2.3 or 3.3.2.
