  I don't think that is a good idea: if you redirect the build output
(as e. g. the bulk builds do), this warning would not be redirected.
One shouldn't break the unix convention of writing to stdout/stderr
without a very good reason.

  That was my thought also.  However, it's not that simple.  For
current NetBSD, the packages will likely build and work, but when
building with gcc from pkgsrc, the run-time dependency on gcc (needed
for the standard C++ shared library) will not be recorded.  So I think
this should be on, even for non-PKG_DEVELOPERs.

  However, the sweep through pkgsrc fixing USE_LANGUAGES should have
been done before turning this on for all users.  But that's largely
water under the bridge now.
