Subject: [PATCH] Fix stdio.in.h with glibc 2.16

stdio.in.h expects that gets is declared but this is not the 
case with ISO C11 anymore which glibc 2.16 follows.

This is a patch to a file that grub takes from gnulib - and is
fixed in upstream gnulib and will thus be in grub2 once this 
file gets regenerated with a newer grub release.

Patch-Mainline: no
