Nothing.  But now try to duplicate the effect of **/*.c, which does
what Alex wants.  The difference between his desired syntax and what's
implemented is that the `**' has to appear on its own as a directory
element to have its special meaning.  Sorry if my rather terse reply
to his question didn't make that clear.
