I don't know how much of a discussion we've had about this. Certainly
we put in some effort for GCC 3.4. I have some module code here
(so that implies hard-float and SCL) and is C++ *and* uses OSLib.
More on what exactly that code is later, but I've done some fixups
in the libstdc++ headers which help actually get a compile.
Apart from that, we need a module version of OSLib and also a module
version of libstdc++ build against SCL (right now we only have
two static versions - hard/soft against UnixLib).
Also, relevant link errors, which I suspect are easy fixes:
