Ahh, I do believe that would work. Actually, I'm not using --make but
the build system I am using (shake) can easily track those
dependencies. It would fix the inconsistent-flags problem because now
I'm not passing any -D flags at all.
It's more awkward though, I'm using make flags or env vars to control
the defines, I would have to either change to editing a config.h file,
or have the build system go rewrite config.h on each run, making sure
to preserve the timestamp if it hasn't changed. But that's not really
all that bad, and you could argue config.h is more common practice
than passing -D, probably because it already cooperates with
file-based make systems.
I'll give it a try, thanks!
