32 bit Clozure + Maxima runs the testsuite OK now



rtest15 test 37 fails with a "Polynomial quotient is not exact" error while doing trigrat. This is due in part to the fact that
trigrat sets gcd to subres.  I think the rtest 15 testsuite failures  193 and 196  are due to the fact that gcd doesn't
properly reset gcd to its default of spmod after the "Polynomial quotient is not exact" error.
