Subject: warning control project status

http://gcc.gnu.org/wiki/Warning%20Message%20Control

Functionality supported:

* Control of warnings through OPT_* values passed to warning().

* Display of command line options corresponding to printed warnings
  through -fdiagnostics-show-option.

Warning conversion:

		# OPT	# Zero	% done

top files	224	175	56 %
all files	306	544	36 %

ada		  0	  1
config		 67	121	36 %
cp		 13	172	 7 %
fortran		  0	  4
java		  2	 19
objc		  0	 51
treelang	  0	  1


Functionality currently planned for 4.2:

* -Werror-foo to turn -Wfoo warnings into errors.  Matching
  -Wno-error-foo for use with -Werror.

* #pragma for limited control of -W* and -Werror-*

The idea behind these is that you'd have a .h file that defines your
"acceptable warnings" policy, that everyone includes right at the top
of each source file, with individual source files being able to make
exceptions.
