Hi Yaffsers

To sweeten things up with an eye to adding YAFFS to the Linux kernel, I have 
split up yportenv.h slightly.

The WinCE stuff now lives in a file called ywinceenv.h in the wince 
sub-directory, and likewise the YAFFS direct stuff has been carved off.

Modified: yportenv.h
Added: wince/ywinceenv.h direct/ydirectenv.h

Regards
