// requires Bit32u/Bit64u from config.h, size_t from stdio.h
//
// Operating system dependent includes and defines for Bochs. These
// declarations can be included by C or C++., but they require definition of
// size_t beforehand. This makes it difficult to place them into either
// config.h or bochs.h. If in config.h, size_t is not always available yet.
// If in bochs.h, they can't be included by C programs so they lose.
