           Summary: importC: extra parentheses in sizeof don't give an
                    error with typedef types

           Version: D2
          Hardware: All

            Status: NEW
          Keywords: accepts-invalid, ImportC
          Severity: normal

typedef int mytype_t;
void fn()
{
        int x;
        x = sizeof( (mytype_t) ); // no error
        x = sizeof( (int) ); // ok: Error: expression expected, not `int`
}

autoconf configure scripts rely on this being an error when determining if a
type is supported:
