c-common.c (STDC_0_IN_SYSTEM_HEADERS, [...]): Default-define here.
* c-common.c (STDC_0_IN_SYSTEM_HEADERS, REGISTER_PREFIX):
Default-define here.
(builtin_define_with_value): Can now wrap the expansion in
quotation marks if such is wanted.
(cb_register_builtins): Update calls to builtin_define_with_value.
Define __REGISTER_PREFIX__, __USER_LABEL_PREFIX__, and __VERSION__
here.
(c_common_init): Set options->stdc_0_in_system_headers.
* c-lex.h: Update prototype of builtin_define_with_value.
* cppdefault.h: Remove default definitions of USER_LABEL_PREFIX
and REGISTER_PREFIX.
* cppinit.c (VERS, ULP, C, X): Kill.
(builtin_array): Remove entries for __VERSION__,
__USER_LABEL_PREFIX__, __REGISTER_PREFIX__, and
__HAVE_BUILTIN_SETJMP__. Make __STDC__ always a builtin, not
a constant.
(init_builtins): Kill off a bunch of now-dead code.
(COMMAND_LINE_OPTIONS): Remove -fleading-underscore and
-fno-leading-underscore.
(cpp_handle_option): Remove code to set user_label_prefix.
(cpp_post_options): Likewise.
* cpplib.h (struct cpp_options): Remove user_label_prefix.
(stdc_0_in_system_headers): New.
* cppmacro.c (builtin_macro): Check CPP_OPTION (pfile,
stdc_0_in_system_headers) too to decide the value of __STDC__.
* tradcpp.c (user_label_prefix): Kill.
(main): Remove code handling -f(no-)leading-underscore.
(initialize_builtins): Don't define __REGISTER_PREFIX__
or __USER_LABEL_PREFIX__.
(install_value): Wrap compound statement in dummy loop so the
macro works properly in an if statement.
