[Bug other/42966] New: add some indication that a warning has been converted to an error

[manu at gcc dot gnu dot org]

See http://gcc.gnu.org/ml/gcc-patches/2009-11/msg01197.html

Currently, warnings enabled by flags are indicated by the flag when using
-fdiagnostics-show-option. However, warnings enabled by default do not show
anything. Two possible fixes:

1) Give the flag that enables the warning (like now). For default warnings, say
"[default warning]". 

2) Give the flag that disables the warning. For default warnings, say "[-w]".

Also, it would be good to move this info after "warning:" (or "error:" if
-Werror=) to make it easier to see/parse.

Of course, anything that does not have a [something] is a hard error that
cannot be disabled.
