All .c files in git are supposed to start by #include-ing
git-compat-util.h, cache.h, or builtin.h to set the appropriate
feature test macros and include system headers.
Headers rely on that for basic types like int32_t. They don't need to
include git-compat-util.h because the .c file that included them would
have already, and .h files #include-ed by git-compat-util.h especially
*shouldn't* #include the compat header, so how about something like
the following for squashing in?
A side-thought: as long as we're building pre-compiled headers, could
we use them in the build?
Thanks,
Jonathan
