-debug output is attached.
`-Wl,-v' only shows the "ld" command. The -debug output has that too.

What's interesting is the "ld" command has "-lgcc-eh" which is where
the missing symbols are defined:
grundler <512>nm libgcc_eh.a | grep _Unwind_SjLj_Resume
0000079c T _Unwind_SjLj_Resume
000008d0 T _Unwind_SjLj_Resume_or_Rethrow
grundler <513>pwd
/usr/lib/gcc-lib/hppa-linux/3.3.1

I wonder if "-Wl,-rpath-link,../../exports/lib" is the problem.
I'd normally expect an application to use "-L" to specify additional
lib search paths.

ok
