In principle it would be best for the options to be completely 
independent.  That is, check_function_arguments would call 
check_function_format if either option is enabled, and 
check_function_format would then only call check_format_info if -Wformat 
is enabled.  (Plus of course removal of the warning for 
-Wmissing-format-attribute on its own, updating of the documentation 
accordingly, removal of gcc.dg/format/opt-6.c which tests for the warning 
and adding a test that -Wmissing-format-attribute on its own enables the 
current warnings.)

Is there a reference to the current statement of this?  
http://gcc.gnu.org/ still points to the 2005-05-04 status report.
