And why not include the file centrally ...

... here you have the inclusion ahead of that of defs.h, so there aren't
any other dependencies (unless something subtle is going on).

Because I intend to delete defs.h entirely.

I've had a bit of fun unpicking __stdcall (looking to remove it
entirely, and replace with fastcall), and we need to shuffle a couple
more macros into macros.h, but all of defs.h can be replaced with
types.h, compiler.h and macros.h

The other problem right now (forcing the order of inclusion here), is
that multiboot*.h implicitly use types.h.
