A thought just occurred to me, you are compiling the entire

If that is the case, you should definitely compile with
-fwhole-program. I suspect that may cut down your compilation
time by half or even more.
I'm back and have spend the last two days trying to get my
project compiled with -fwhole-program in an effort to reduce the
compile times, but I haven't had any success.
Regardless of what I do, the compiler doesn't emit anything
except main.

Are you sure this works with multiple modules passed to the
compiler on one line?
