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.
