GCC runs OK on SGIs, provided that you have a version that coexists
with the version of IRIX that you're running (later (3.2+) versions
don't like pre-5 IRIXes. GCC will likely be quite unsatisfactory,
though, because the optimization on MIPS machines is not very good, and
especially bad with 2.x versions. Pre 3.4 versions don't play nicely
with MIPSpro/MIPSCC object code, either.
SPARC is better, indeed for C++ or ANSI C on SunOS4 you will probably
have to use gcc, since Sun's ANSI and C++ compilers are both hard to
come by and nodelocked.
POWER/PowerPC is probably the best of the RISCs as far as GCC support
goes. Apple's adoption of gcc for System 10 led to a number of
improvements in the code generator for PPC.
