2012-01-07 Ulrich Drepper <drepper@gmail.com>
* iconv/gconv_builtin.h: Use CHAR16 for the char16_t conversions.
* iconv/gconv_simple.c: Rename char16_t routines. Add char16_t<->utf8
routines.
* iconv/gconv_int.h: Adjust prototypes for char16_t routines.
* iconv/iconv_prog.c: Recognize CHAR16 as internal name.
* wcsmbs/c16rtomb.c: Fix a few problems. Disable all the code and
fall back to using wcrtomb.
* wcsmbs/mbrtoc16.: Fix implementation to handle real conversions.
* wcsmbs/wcsmbsload.c: Make char16 routines optional. Adjust for
renaming.
* wcsmbs/Makefile (tests): Add tst-c16c32-1:
* wcsmbs/tst-c16c32-1.c: New file.
* wcsmbs/wcrtomb.c: Use MB_LEN_MAX instead of MB_CUR_MAX for sizing
local variable.
* libio/stdio.h: Do not declare gets at all for _GNU_SOURCE.
* elf/tst-unique3.cc: Add explicit declaration of gets.
