I'm not sure from your message whether you're actually interested
in MIPS or not, but for the record:
I don't think MIPS/-mint64 is really an official target. There's no
well-defined MIPS ABI that uses 64-bit integers and it's unclear whether
anyone thought through the consequences of taking an official ABI and
slapping a 64-bit int onto it. (I'm talking about the impact on gcc
internals as well as user expectations here.)
FWIW, EricC and I were wondering about phasing it out...
