I've committed a quick fix now. I'm not proud of it, but let's see if
it works first. Among other things, I've simply *disabled* the wchar_t
tests when BOOST_NO_STD_LOCALE is defined. I don't like this at all:
it implies we have different sets of tests for different platforms and
even let libraries that do not support <locale> appear better (in the
regression logs) than libraries that support it with some failures. Is
there any boost policy for this? Maybe I should put the wchar_t tests
in a separate file and mark that one as unusable for platforms with no
<locale> support? Still, for Metrowerks that would be a problem,
because the library, in general, *does* support locale; it just
disables it in some configurations.

Genny.
