libstdc++ and missing <wctype.h>

libstdc++ and missing <wctype.h>

[Robert Lipe]

A few days ago, libstdc++ stopped building on OpenServer.   I finally
got a chance to investigate it.

The problem is that there isn't a file <wctype.h>.  (There is one on SVR5
and on the UDK targets.)  My copy of Plauger's "Standard C Library"
doesn't say there has to be one, so I think we should be prepared to
deal with its absence.

I can't find evidence of an autoconf-ish mechanism in libstdc++/.   Can
anyone advise me how to best address this?
