RC2 seems to be good on powerpc-darwin8,

<http://gcc.gnu.org/ml/gcc-testresults/2005-06/msg01175.html>

compared to

<http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01328.html>

except that the testcase

libstdc++-v3/testsuite/26_numerics/cmath/c99_classification_macros_c.cc

appears to fail, with lots of complaints like

c99_classification_macros_c.cc:49:21: error: macro "isgreaterequal" requires 2 arguments, but only 1 given

but the actual file did this with previous versions too, I think
something changed in the test harness.  As far as I can tell, this
testcase is in fact invalid and should produce exactly this error
message.
