Porting GCC to RDOS and C++ issues

["Leif Ekblad" <leif at rdos dot net>]

I've successfully ported GCC and Newlib to RDOS. It seems to work with a 
"hello world" app.
However, my main focus is not C, but C++.

I found out that libstdc++ didn't compile without modifying it's 
configuration files to support RDOS.
Where do I send patches for libstdc++? To this list?

However, now I still get unresolved externals related to C++ 
exception-handling (_Unwind_resume
and so on). Where are these functions implemented, and does there exist some 
example implementations
of these? Why can't newlib or libstdc++ implement these functions? Or have I 
simply misconfigured
libstdc++? The configure script for libstdc++ is *huge* and largely 
incomprehensible. I used the same
ABIs as gnu and linux uses to get it to compile.
