As a final note on this bug, the core dumps disappear on
mips-sgi-irix if I start from the beginning with 64bit code, i.e.
mips64-sgi-irix.

By setting -mabi=64 in CFLAGS, longs become 8 bytes, and
bugs disappear. No need for my hack of tricking gmp into using 32
bit mips asm. This solves the package.conf bug, the __decodeFloat
bug and the gmp div bug that mips people have encountered. 

So we'll see how far we get using 64 bits right from the start on
this funny Irix thing.
