-	* gcc.c (spec_undefvar_allowed): New global.
-	(process_command): Set to true when running for --version or --help
-	alone, or together.
-	(getenv_spec_function): When the variable is not defined, use the
-	variable name as the variable value if we're allowed not to issue
-	a fatal error.
+	* gcc.c (process_command): When deciding if undefined variables
+	should be ignored when processing specs, accept "gcc -v" as well.
