Yes, if we still need it but I found another approach.

It turns out these prototypes are expected in "unistd.h" file. The
platform doesn't have it so Mark and I created "windows-NT/unistd.h"
sometime ago. I committed a patch that dropped prototypes we added
in favor of including "direct.h" and "io.h" which is where Microsoft
has a lot of what is normally found in "unistd.h" which improved the
warning count significantly.
