[ACCEPTED]-gcc -W warning flags-gcc

Accepted answer

Score: 19

-W is now deprecated by -Wextra with new gcc versions.

From 1 gcc man page:

   -Wextra
       This enables some extra warning flags that are not enabled by -Wall.
       (This option used to be called -W.  The older name is still supported, but
       the newer name is more descriptive.)
