2.95.4, sparc64 issues ?

[Marc Espie]

It seems that libstdc++ does not compile on every sparc64 machine,
and that the following patch (from current) might be enough to fix it ?

Took this diff from gcc not-really-current-but-almost cvsweb.

Seems to allow libstdc++ to at least compile.

Targeting -m64 on sparc with gcc 2.95.x is a bad idea, this is not the only
place which needs changing.

It might be a bad idea, but gcc 3.0.1 is still broken, and we won't be able 
to change compilers on OpenBSD before it looks somewhat usable.
