I have tested small script testunix.m under octave on cygwin (under 
/usr/share/octave/3.2.3/m/plot
directory).

if (isunix())
 disp('unix')
else
 disp('not unix')
end
if (ispc())
 disp('pc')
else
 disp('not pc')
end

*** result is
octave:2> testunix
unix
not pc
****

The above tells that isunix() is true on cygwin so that further patch is not 
needed for print()
function.

Thank you for your comments. I will consider the changeset after dinner :-).
