	* include/cpplib.h (TTYPE_TABLE): Remove CPP_ and SPELL_
	prefixes throughout.  Add entry for PRAGMA.  Remove
	unnecessary "= 0" from EQ.
	(enum cpp_ttype): Adjust OP and TK definitions to restore
	prefixes, via token-paste.
	(CPP_LAST_EQ, CPP_FIRST_DIGRAPH, CPP_LAST_PUNCTUATOR, CPP_LAST_CPP_OP):
	Change from #defines to additional cpp_ttype enumerators.
	(struct cpp_options): Add defer_pragmas.
	(cpp_handle_deferred_pragma): Prototype new interface.

	* internal.h (struct cpp_reader): Add directive_result.
	* directives.c (struct pragma_entry): Add is_internal field;
	give boolean fields type bool.
	(start_directive): Initialize pfile->directive_result.type.
	(_cpp_do__Pragma): Likewise.
	(run_directive): Do not crash if pfile->buffer->prev is NULL.
	(insert_pragma_entry): Add 'internal' argument; set new->is_internal
	from it.
	(register_pragma): New static function, bulk of former
	cpp_register_pragma here; add 'internal' argument, pass along
	to insert_pragma_entry.
	(cpp_register_pragma): Now a wrapper around register_pragma which
	always passes false for 'internal' argument.
	(_cpp_init_internal_pragmas): Call register_pragma directly, passing
	true for 'internal'.
	(do_pragma): If CPP_OPTION (pfile, defer_pragmas) and this isn't
	an internal pragma, save text till the end of the line as a CPP_PRAGMA
	token instead of executing the pragma.
	(cpp_handle_deferred_pragma): New interface.
	* lex.c (token_spellings): Adjust OP and TK definitions to
	match changes to cpplib.h.
	(_cpp_lex_token): Check for a directive-result token and
	return it if present.
	(cpp_token_val_index): Handle CPP_PRAGMA.
	* macro.c (cpp_builtin_macro_text): Correct comment.
	(builtin_macro): Handle directive-result tokens from _cpp_do__Pragma.
