/**
 * see rationale in wposix.h.
 * prevent subsequent includes of CRT headers (e.g. <io.h>) from
 * interfering with previous declarations made by wposix headers (e.g. open).
 * this is accomplished by \#defining their include guards.
 * note: \#include "crt_posix.h" can undo the effects of this header and
 * pull in those headers.
