Thank you for the suggestion though unfortunately not every build system

the source files in at once when I want a full rebuild.
You can easily write a rule for make to perform a rebuild. For example,
most makefiles I've used include a "clean" target, which deletes all
generated files (.o, .exe, etc), as well as an "all" target that builds
everything that needs to be built. Combining those two to implement
"rebuild" is as easy as:
rebuild: clean all
At least, I think that's the proper syntax. It's been a while since I
created a makefile from scratch.
I'd imagine this is a rather easy feature to add to gcc, if I were to
implement this and submit a patch for it, would it be accepted? (assuming
coding style and etiquette are followed)
I can't answer whether it would be accepted or not, since I don't work
on gcc. However, I still think your time would be much better spent
learning how to use make (or some similar tool) instead.
Another big benefit of using make is that it can perform multiple tasks
(compiles) in parallel, to speed up builds. Naturally, this can be
especially helpful on multiprocessor/core machines.
Here are a few links to tutorials about make (and GNU make):

Good luck!
