If this is the way, then #define TO_BOOL(thing) (!! (thing))

(does uncrustify then change this to (! ! (thing)) ?

Alternative is to do (bool) cast -- i.e. return (bool)opt_desc->opt_inherit + (bool) ...

-- for the question in PATCH 0 -email:

I'd prefer just one commit doing all the uncrustify changes for now, and
preferably set 

GIT_AUTHOR_NAME=uncrustify

(GIT_AUTHOR_EMAIL not modified)

this way anyone who does git annotate can easily see who not to blame for
changes and notice what such style changes was done at the same time...

after first big bump in it is easier to fix some leftover smaller things
(if any) -- incrementally, as the effort required is significantly smaller...


I'm not sure whether TO_BOOL looks so good, but these changes LGTM. someone
more familiar seeing '!!' in other codebases could comment??
