Subject: mkimage: make it easier to run syntax checkers on grub-mkimagexx.c
X-Git-Url: https://iam.tj/gitweb/gitweb.cgi?p=grub.git;a=commitdiff_plain;h=352868d1234c94393e84871072372d73cb1166fa

mkimage: make it easier to run syntax checkers on grub-mkimagexx.c

This makes it so you can treat grub-mkimagexx.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 -W 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.
