2000-07-25  Benjamin Kosnik  <bkoz@gnu.org>

	* bits/std_fstream.h: Parameterize __basic_file.
	* config/c_io_libio.cc: Add wchar_t methods for parameterization.
	* bits/basic_file.h: Same here.

	* bits/fstream.tcc: Shorten __retval to __ret.
	* bits/ostream.tcc: Same.
	* bits/sbuf_iter.h: Same.
	* bits/sstream.tcc: Same.
	* bits/streambuf.tcc: Same.
	* bits/std_fstream.h: Same.
	* src/string-inst.cc: Same.
