[PATCH v4 1/1] grub-module-verifierxx.c: enable running standalone checkers

[Robbie Harwood]

From: Peter Jones <pjones@redhat.com>

Allow treating grub-module-verifierxx.c as a file you can build directly
so syntax checkers like vim's "syntastic" plugin, which uses "gcc -x c
-fsyntax-only" to build it, will work.

One still has to do whatever setup is required to make it pick the right
include dirs, which -I options we use, etc., but this makes it so you
can do the checking on the file you're editing, rather than on a
different file.
