Whoooohoooooo! Thanks Jakub. Thanks also for adding the testcase.

You can use setlocale("C") to force to the "C" locale. If you look at
the libstdc++/testsuite/22_locale tests, most of them do this. (At
least for some tests.)

Anyway.

I've long been puzzled by these. They appear and then disappear for no
reason on powerpc: at first I thought they were endian issues with the
library code, but then I saw correct results from powerpc (before they
went bad again.)

alpha, ia64, others get these two tests right. I dunno what's up.
