No; the header exists, but it doesn't declare sleep(). The <stdlib.h>
header declares _sleep(), although apparently this is deprecated (it
exists in the MSVCRT DLL, but isn't listed in the documentation index)
in favour of Sleep().

Only if you don't have "ls" ;)

A lot of the [G_]system and [G_]popen calls in GRASS (I count 105)
will be similarly problematic. Some will be calling GRASS programs,
but a lot use Unix commands.
