With the enclosed patches I can run libg++/tests/test0 to successful
completion on a sun386 with g++ using COFF encapsulation.  Your line
numbers will probably be different; I started with ld.c from
g++-1.36.1, but I added patches for 68020 UTek (tek4300).

I have also run all of the other tests in libg++/tests/ through sun386
g++; only tRandom generates output different from what a sparc
generates; apparently tRandom's results are machine-dependent.  My
recent postings to bug-gnu-utils and bug-gcc (gnu.utils.bug and
gnu.gcc.bug) contain most of what is necessary to build COFF
encapsulation g++ on a sun386, beyond the relevant GNU sources.
