  if (isunix ())
    persistent ghostscript_binary = "gs";
  elseif (ispc ())

If isunix() is false on cygwin, print() function shoud look for "gs.exe" 
because "gs.exe" is default
ghostscript command on cygwin.


BTW, what I thought about why cygwin is included in the 'case esac' after the 
first post. I suspect
that the 'case' here cares cygwin users who use native windows version 
ghostscript but do not use
cygwin version of ghostscript.


However is this kind of care really necessary?  

If it is necessary, the 'case esac' is to be 
****   
  case "$canonical_host_type" in
    *-*-cygwin* | *-*-mingw32* | *-*-msdosmsvc)
      gs_names="gs gswin32c"
    ;;
    *)
      gs_names=gs
    ;;
  esac
*******
otherwise,
****   
  case "$canonical_host_type" in
    *-*-mingw32* | *-*-msdosmsvc)
      gs_names="gswin32c"
    ;;
    *)
      gs_names=gs
    ;;
  esac
*******

It would be better to hear Marco's comments.  Marco is the maintainer of the 
cygwin version of the
octave.
