It looks like you customized indent-tabs-mode to nil in C modes (or
maybe don't use Emacs?) because your indentation uses only spaces.
Please use our conventions in C sources, which uses TABs and spaces,
per indent-tabs-mode's default value.

This is a general comment, because I see signs of this in all of your
patches.
