The general rule I'm aiming for is to <> include system wide / installed paths / generally everything that's outside the git managed source tree (this means mruby paths too!), and "" include everything else, ie. local mkxp headers. The only current exception are the mri headers, which all have './' at their front as to not clash with system wide ruby headers. I'm leaving them be for now until I can come up with a better general solution.
