2002-04-30 Roland McGrath <roland@frob.com>
Removed old GNU stdio implementation; GNU libio is now the only option.
* configure.in: Removed --enable-libio option and @stdio@ subst var.
Define USE_IN_LIBIO unconditionally.
* configure: Regenerated.
* Makeconfig (stdio): Set to libio by default.
* config.make.in (stdio): Variable removed.
