Just FYI,

I tried to build pkgsrc/lang/gcc3-c on my dreamcast,
and it works with the following patch:
(it requires --disable-shared on configure)

But lang/gcc3-c++ fails with the following errors during
configure in libstdc++-v3:

---
[...]

Maybe we should pass --disable-sjlj_exceptions to
libstdc++-v3/configure, but I don't know how to fix it..
