Things are looking better on Mac OS X. With some tweaks I get the following from 'make check-gm2':

# of expected passes            6084
# of unexpected failures        54
# of unresolved testcases       18

One tweak is the following patch (ld on OS X complains about the dwarf format):

Another is to replace '--strip-underscores' by '--strip-underscore' in gcc-4.1.2/libstdc++-v3/scripts/ The manpage refers to the plural but c++filt only takes the singular. I haven't created a patch because I'm hoping it might be fixed with an upgrade to Xcode (I'm running 3.0).

Finally, I needed to do a 'make install' before running the tests. The C++ library (-lstdc++) wasn't being found by the linker. There is undoubtedly a proper fix which can be applied in the Makefile.
