2000-08-22 Benjamin Kosnik <bkoz@purist.soma.redhat.com>
* src/locale-inst.cc: Add codecvt<unicode_t, wchar_t,
__enc_traits> instantiations for has_facet and use_facet.
* testsuite/22_locale/codecvt_unicode_wchar_t.cc: New file, for
testing two-byte unicode encodings converted to four-byte UCS4
encodings.
* bits/codecvt.h (codecvt<__enc_traits>): Fix do_unshift.
* testsuite/22_locale/codecvt_unicode_char.cc (test01): Add
correct state/encoding information.
* acinclude.m4 (GLIBCPP_CHECK_WCHAR_T_SUPPORT): Add wcsrtombs,
mbsrtowcs checks as codecvt<wchar_t, char, mbstate_t> needs them
now.
Add checks for langinfo.h, nl_langinfo function call.
* libio/iofwide.c (_IO_fwide): Simplify, as nl_langinfo is assumed.
