Progress: featureless make.

Progress: featureless make.

Begin adding support for more complicated section operations.
Add break/exit to allow for manually exiting or breaking.

The error/warning systems needed to be rewritten to handle additional situations where "fail" mode is set to "warn" or "ignore" instead of "exit".
Errors may need to be warnings or not printed at all.

I noticed that I have been, perhaps habitually, using the system include path logic for including headers in the local source.
This is dangerous.
Avoid the possibility of including headers from the system that are actually headers provided by the project itself.

Other minor fixes and cleanups.
