Hi Eli,

This is quite an intriguing idea.

The underlying functionality is different in win32. The examples you
put are typical cases where one wanders if it is not better to use
native functions...

Of course, porting from Unix platforms has always been taken into
consideration, in DOS before and in win32 after. However, there is
no win32 unistd.h, except for various projects that had a "win32/unistd.h"
(can google that string) where they used to put just a few missing bits,
e.g. define S_ISREG or declare usleep(). Hmmm...
