In fact I am totally newbie. However my final target
is 64bit apps. Hence I am setting modest target of
N32. That is why I am not really thinking about N64 or
tru64 kinda support.

I have tried to compile in SDE toolchain for NetBSD.
It worked to a level after that I gave because some
how I could not add N32 support to it. I combined
Algor + DEC MIPS NetBSD combination to get the final
toolchain. It seems the N32/N64 can be compiled only
on IRIX platforms. In your idea is there anybody
working on this already??
