toplev.c (documented_lang_options): Add -fshort-wchar.
* toplev.c (documented_lang_options): Add -fshort-wchar.
* c-decl.c (c_decode_option): Likewise.
(init_decl_processing): If -fshort-wchar, use 'short unsigned int'
for wchar_t.
* c-common.c, c-lex.c: Get WCHAR_TYPE_SIZE from wchar_type_node.
* gcc.c (default_compilers): If -fshort-wchar,
override __WCHAR_TYPE__.
* tm.texi (C Dialect Options): Add -fshort-wchar.
