I'm not sure this is relevant to any decision to import this but
as far as I know the nios2 port of gcc is not is part of the main gcc
release.
(If it was it would be easier to get fixes applied!)

I'm also not entirely convinced that Linux is an appropriate
operating system for a 100MHz nios2 cpu. You'll certainly have
problems processing Ge data rates (and maybe 100M ones as well).
