           Summary: Please add an option to catch empty statements
                    (-Wempty-statement ?)
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: austinengl...@gmail.com


It would be useful to have an option to catch empty statements, e.g.:

#include <stdio.h>
int main(void)
{
    ;;
    return 0;
}

a la -Wempty-body does currently.

I've seen this happen a few times recently in Wine, especially when expanding
macros, e.g,.:
