Yes, sure, large projects can take time to compile, but doesn't your compile environment just try to recompile the last file that it failed on during the build? That is, if in trying to build my app FooBar, and foo.c compiles ok but bar.c fails, when I try to run the build the next time having modified bar.c, it starts by trying to compile bar.c anyway... So I guess what I'm trying to say is that I don't understand the advantage you are apparently getting by woring from bottom up.

I don't want to get into the specifics of the build system since it's proprietary, but there's a non-trivial startup cost for it. It's optimized for being able to compile really huge projects in a tractable amount of time, not being able to recompile individual files in the shortest possible amount of time. The latter will execute quickly enough (yes, it only recompiles what you've changed), but the startup time is still annoying enough to want to batch up edits.
