[multiple changes]
2000-08-09 Benjamin Kosnik <bkoz@purist.soma.redhat.com>
Preliminary wchar_t implementation, with trivial encodings.
* docs/configopts.html: Add bits about canonical configure option
checking.
* testsuite/27_io/iostream_objects.cc: Replace this file (which
has newly-declared-illegal mixing of wide/narrow stdstreams) with...
* testsuite/27_io/narrow_stream_objects.cc: New file.
* testsuite/27_io/wide_stream_objects.cc: New file.
* bits/fstream.tcc (underflow): Temporarily hack a solution
together that writes from the external file to the internal
buffers. This removes codecvt from the loop, and is incorrect.
(_M_really_overflow): Same here.
* testsuite/21_strings/inserters_extractors.cc (test05): Tweaks.

Ulrich Drepper <drepper@cygnus.com>
* config/c_io_libio.h: Tweak.
* config/c_io_libio_codecvt.c: New file.
* libio/Makefile.am: Add c_codecvt.c.
* libio/Makefile.in: Regenerate.
* libio/genops.c (_IO_unbuffer_write): Don't call _IO_SETBUF if the
stream is not orientated.
* acinclude.m4: Add config/c_io_libio_codecvt.c dummy file, until
encoding gets fleshed out.
* bits/basic_file.h: Add specialization declarations.
* config/c_io_libio.cc: Add specializations for pbackfail, uflow.
* config/c_io_libio.h: Add __c_wfile_type.
* bits/basic_file.h: Add _M_wfile.
* config/c_io_libio.cc (__basic_file<char>): Initialize the
streams without setting the orientation of the underlying FILE to
either wide or narrow.
(__basic_file<wchar_t>)): Enable tricky wchar_t io bits.
