Thanks, I saw the patch you posted (which looks good to me, FWIW).
Using { dg-require-effective-target ilp32 } would certainly fix the
bogus MIPS failures.  Maybe it'd be worth adding a new keyword like
"ipXX" (or whatever) to indicate that pointers and integers are the
same size, but there again, maybe that would be overkill.  I don't
mind either way.
