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. 2000-08-08 Benjamin Kosnik <bkoz@cygnus.com> 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. From-SVN: r35584
