------- Comment #3 from manu at gcc dot gnu dot org  2010-03-03 15:36 -------
Use -fdiagnostics-show-option to see which option controls a warning. In this
case, it will show nothing (this is another bug that will be fixed in GCC 4.6)
because, unfortunately, this is a default pedantic warning, so right now your
only choice is to use -pedantic-errors. I turned this to a feature request to
add an option to control the warning, for example, -Wdiscarded-qualifiers. 

This is trivial but trunk is on regressions-only mode, so it won't be available
until GCC 4.6.
