	AH = 39h
	DS:DX -&gt; ASCIZ pathname
Return: CF clear if successful
	    AX destroyed
	CF set on error
	    AX = error code (03h,05h) (see <a href=../../it/80/16.html>#01680</a> at AH=59h/BX=0000h)
Notes:	all directories in the given path except the last must exist
	fails if the parent directory is the root and is full
	DOS 2.x-3.3 allow the creation of a directory sufficiently deep that
	  it is not possible to make that directory the current directory
	  because the path would exceed 64 characters
	under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
