2 locations won't help you either.
void foo ()
{
#define EMPTY
while (0)EMPTY;
}
won't warn when compiled with g++ -Wempty-body -O2, but will with
g++ -Wempty-body -O2 -save-temps (i.e. ccache etc.). I think it is unfortunate
this -Wempty-body extension was accepted for 4.3, and if we want to make it
work, we really have to handle it at the preprocessor level.-- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36478
