Details:

In testing Octave built for i686, I am seeing 3 test failures in betainc.m, 1
test failure in cosint.m, 5 test failures in gammainc.m, and 2 test failures
in sinint.m.

All of these test failures look like candidates for increasing the tolerances,
if someone familiar with these functions can verify that this makes sense.
