Using -Wl,-v, I see:

/test/gnu/gcc-3.3/objdir/gcc/crtbeginT.o:
    _Jv_RegisterClasses is DEFINED WEAK FUNC
    __dso_handle is DEFINED GLOBAL OBJECT
    __deregister_frame_info is UNDEF WEAK FUNC
    __register_frame_info is UNDEF WEAK FUNC

Selecting /test/gnu/gcc-3.3/objdir/gcc/libgcc_eh.a[unwind-dw2-fde.o] to resolve
__register_frame_info

Bah, this would appear to be a HP linker bug.  The linker isn't supposed
to extract archive members to resolve undefined weak symbols.
