c-common.c (c_common_init): Set options->unsigned_char from flag_signed_char.
* c-common.c (c_common_init): Set options->unsigned_char from
flag_signed_char.
(cb_register_builtins): Define __STRICT_ANSI__ and
__CHAR_UNSIGNED__ here...
* cppinit.c (init_builtins): Not here.
(cpp_create_reader): unsigned_char option defaults to 0, not
!DEFAULT_SIGNED_CHAR.
(COMMAND_LINE_OPTIONS, cpp_handle_option): Lose -fsigned-char
and -funsigned-char.
* cpphash.h (struct spec_nodes): Kill n__STRICT_ANSI__.
* cpphash.c (_cpp_init_hashtable): Don't set it.
* cppmacro.c (builtin_macro) [BT_STDC]: Use the language setting
directly. Clarify comment.
