Manuel López-Ibáñez 71205d170c re PR other/36901 (pedwarn() + -pedantic-errors + -w (inhibit_warnings) should not emit errors)
2008-08-09  Manuel Lopez-Ibanez  <manu@gcc.gnu.org>

	PR 36901
	* diagnostic.def (DK_PEDWARN, DK_PERMERROR): New.  
	* diagnostic.c (pedantic_warning_kind, permissive_error_kind):
	Moved from diagnostic.h
	(diagnostic_report_diagnostic): Return bool. Handle DK_PEDWARN and
	DK_PERMERROR.
	(emit_diagnostic): New.
	(warning0, pedwarn0): Delete.
	(warning, warning_at, pedwarn, permerror): Return bool.  
	* diagnostic.h (pedantic_warning_kind, permissive_error_kind):
	Moved to diagnostic.c.
	(struct diagnostic_context): Use correct type for
	classify_diagnostic.
	(diagnostic_report_diagnostic): Update declaration.
	(emit_diagnostic): Declare.
	* errors.c (warning): Return bool.  
	* errors.h (warning): Update declaration.
	* toplev.h (warning0, pedwarn0): Delete.
	(warning, warning_at, pedwarn, permerror): Return bool.
	* c-errors.c (pedwarn_c99, pedwarn_c90): Use DK_PEDWARN.
	* c-decl.c (locate_old_decl): Delete 'diag' argument. Always use
	inform. Update all calls.
	(diagnose_mismatched_decls): Check return value of warning/pedwarn
	before giving informative note.
	(implicit_decl_warning): Likewise.  
	* c-typeck.c (build_function_call): Likewise.  
	* tree-sssa.c (warn_uninit): Likewise.  
	* builtins.c (gimplify_va_arg_expr): Likewise.
fortran/
	* f95-lang.c (gfc_mark_addressable): Use "pedwarn (0," instead of
	'pedwarn0'.
cp/
	* cp-tree.h (struct diagnostic_context, struct diagnostic_info):
	Delete forward declarations. Check that toplev.h has not been
	included before this file. Include toplev.h and diagnostic.h.
	* error.c (cp_cpp_error): Use DK_PEDWARN.
	(cxx_incomplete_type_diagnostic): Update declaration.
	(cxx_incomplete_type_error): Use DK_ERROR.
	* typeck2.c (cxx_incomplete_type_diagnostic): Take a diagnostic_t
	as argument. Use emit_diagnostic.
	(cxx_incomplete_type_error): Use DK_ERROR.
	(add_exception_specifier): Use diagnostic_t instead of custom
	codes.  
	* typeck.c (complete_type_or_else): Update call to
	cxx_incomplete_type_diagnostic.
	* init.c (build_delete): Likewise.  
	* call.c (diagnostic_fn_t): Remove unused typedef.
	(build_temp): Pass a pointer to diagnostic_t.
	(convert_like_real): Use emit_diagnostic.
	(joust): Check return value of warning before giving informative
	note.  
	* friend.c (do_friend): Check return value of warning
	before giving informative note.
	* parser.c (cp_parser_template_id): Likewise.
