Re: build failure (from configure patch?)

Unfortuntely not.  I've been looking closer now; it seems that the
various wchar-related configure tests are for whether or not wchar.h
defines certain features; there is no test done solely for whether wchar.h
even exists.  The former tests fail (corectly), but not for the reason
that we think.

What dies later on is bits/std_cwchar.h, when it has "#include_next
<wchar.h>" with no surrounding test to see if the #include should be done.

It may well be that this particular Linux box is horked up (I don't admin
this one, sorry...).  There is no wchar.h anywhere on the system at all
except for the shadowing header in the libstdc++ sources.  Somebody who
actually keeps track of wide character concepts (I sure don't) will have
to tell me if that's normal or broken; whether a missing wchar.h is to
be expected or not.
