Although I know Octave-Forge is more lax about coding standards, I
don't think this sort of macro checking is a good idea. Instead, in
configure.ac we can do

         AC_CHECK_HEADERS([unistd.h])

and then use

    #if HAVE_UNISTD_H

instead.

If you don't know how to do this, I can do it myself, but I'm busy
with other things right now.
