            Bug ID: 89926
           Summary: -Wmain warning about return type doesn't show location
                    of the return type
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: minor
          Priority: P3
         Component: c

As I observed in bug 83797 comment 4, this location looks wrong:

vm.c:1:6: warning: return type of ‘main’ is not ‘int’ [-Wmain]
 void main() { }
      ^~~~

I would expect:

vm.cc:1:6: warning: return type of ‘main’ is not ‘int’ [-Wmain]
 void main() { }
 ^~~~
