Use of gccfss-4.3.3 is not an improvement.
Instead of failing the atomic_cmpset test, the compiler HANGS when
compiling atomic_cmpset.c.
I allowed the compiler just over 4 hours accumulated CPU time before
being convinced it was hung.
So, I'd like to request documenting "gccfss" as unusable in README.
This is important because this broken compiler is installed as
/usr/bin/gcc on some Solaris systems.
