Thanks, done.

I did see ctype_members_char and considered adding my test to that
file, however I noted that it is currently contains this:

	// XXX This test (test02) is not working for non-glibc locale models.
	// { dg-do run { xfail *-*-* } }

This makes adding my test to it useless as a mechanism for catching
broken scan implementations.

IMHO, the convention of adding test#() functions to existing
libstdc++-v3 tests is really a bad idea, since you lose every test in
the file when it's marked xfail like this.  We should consider
breaking out every test#() function into its own main() in its own
file.  Or at least do so for tests marked xfail so the other test
functions in that file get checked properly and appear as real
failures if they break.

Yes, I'll have to pass on the wchar test.  So I accept your offer to
do it instead. :-)
