The same phenomenon occurs on gnuplot on Ubuntu 14.04 LTS.
gnuplot> set terminal postscript lw 1.5; set output 'ps_symbols.ps'
Terminal type set to 'postscript'
Options are 'landscape enhanced defaultplex \
   leveldefault monochrome colortext \
   dashlength 1.0 linewidth 1.5 butt noclip \
   nobackground \
   palfuncparam 2000,0.003 \
   "Helvetica" 14  fontscale 1.0 '
                                         ^
         unrecognized option

gnuplot> 

The above seem to be platform independent.
