Re: [PATCH v2 0/3] C99: declare bool experiment a success

[off-list ref] writes:

bool is not standard in all c99 implementations. I have to #include <stdbool.h> in order to
use this type. Please make sure there is a mechanism for that.

Given that <git-compat-util.h> unconditionally includes
<compat/posix.h> and <compat/posix.h> unconditionally includes
<stdbool.h> even in today's code, that should be OK.
