You'd better map to integers that do not collide with ascii characters
(even if non printable).
So values >= 256 are better.
This is the reason for the comment here:

You can concatenate the macro.

-       printf("usage: %s [EAL options] -- --pdump "
+       printf("usage: %s [EAL options] -- [--"CMD_LINE_OPT_MULTI"] "
