I would like to see retro_inline.h moved in here; possibly boolean too.
rationale: these are used in public APIs, and it is easier to find problems
and write code that works the first time portably when theyre included uniformly
than to do the analysis from scratch each time you think you need it, for each feature.
Moreover it helps force you to make hard decisions: if you EVER bring in boolean.h,
then you should pay the price everywhere, so you can see how much grief it will cause.
Of course, another school of thought is that you should do as little damage as possible
in as few places as possible...

This file is designed to create a normalized environment for compiling
libretro-common's private implementations, or any other sources which might
enjoy use of it's environment (RetroArch for instance).
This should be an elaborately crafted environment so that sources don't
need to be full of platform-specific workarounds.
