While I fail to see an immediate connection between glibc bug #326581
that caused uic to bus error, and the illegal instruction in libgcc2's
__umoddi3(), I'm also aware of my complete ignorance of hppa
peculiarities and resist the temptation to put blame on gcc-4.0 or
binutils for this bug. ;-)

Anyway, I while trying to debug why uic fails on some files but works
fine with others, I noticed that a test .ui file with

	<!DOCTYPE UI><UI version="3.0"></UI>

compiles just fine with uic on paer. Anything with a version less than
3.0, or no version identifier at all leads to a SIGILL. So if you're in
dire need to work around this bug, upgrading .ui files to a later
version might be an option.
