This function has been defined in pg_wchar.h for a long time, and is
certainly not deprecated. OTOH I don't think it makes much sense to put
that function declaration in libpq-fe.h, because it's not exclusive of
frontends.

The correct solution seems to be that the libpq-dev package must include
mb/pg_wchar.h. Not sure how reasonable that is for your package set; if
there's a package with the rest of the headers, probably it'll have to
depend on libpq-dev or something.
