No, simply a little tired, sorry.

I was just a little puzzled because on MIPS there is no inline-assembler
anyway and you have this nice "ARCH_IS_GENERIC" define etc, but then 
in portab.h everything except gcc, MSVC++ and icc is simply kicked out. 

I search a little at google and found that __sgi is the Define I had to
check for. Adding this in the GCC/ICC section worked as well, but I really
prefer a "generic compiler" section.

If we don't want to rely on C99, I'll have to change a few lines in new GMC. 
Good to know...
