*
*Purpose:
*	defines _rmdir() - remove a directory
*
*Revision History:
*	06-06-89  PHG	Module created, based on asm version
*	03-07-90  GJF	Made calling type _CALLTYPE2 (for now), added #include
*			<cruntime.h>, fixed compiler warnings and fixed the
*			copyright. Also, cleaned up the formatting a bit.
*	03-30-90  GJF	Now _CALLTYPE1.
*	07-24-90  SBM	Removed '32' from API names
*	09-27-90  GJF	New-style function declarator.
*	12-04-90  SRW	Changed to include <oscalls.h> instead of <doscalls.h>
*	12-06-90  SRW	Added _CRUISER_ and _WIN32 conditionals.
*	01-16-91  GJF	ANSI naming.
*	04-06-93  SKS	Replace _CRTAPI* with __cdecl
*	11-01-93  CFW	Enable Unicode variant, rip out Cruiser.
*	02-08-95  JWM	Spliced _WIN32 & Mac versions.
