commit 256b19184bcb05c3cd9a6061730b7d67d61c0763
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Sat Dec 6 22:29:51 2014 +0100

    Repeat execvpe(3) prototype (fup to 7bad9d7d52d)
    
    This is needed in case `<unistd.h>` was included before "execvpe.h"
    w/o `_GNU_SOURCE` set (on Glibc systems)
