Yes, I'd like a wchar module that provides wchar.h, so that we can
remove HAVE_WCHAR_H from most of the code.

In practice I'd guess almost all GNU targets have <wchar.h> these
days.  But there's a caveat: the C standard does not require <wchar.h>
of freestanding implementations, and officially GCC is freestanding.
It could be that some libraries using gnulib will want to port to
small environments that lack the full C library.  I admit I'm waving
my hands here, though; I don't personally know of such an environment
being used as a GNU target.
