・・・中略・・・
This program has been compiled using Microsoft Visual C++ 4.0 with the
following command line:
cl /O2 pgnuplot.c /link user32.lib
The resulting program has been tested on WinNT and Win98 both by calling
it directly from the command line with and without redirected input. The
program also works on WinNT with a modified version of Gnuplot.py (a script
for interactive control of Gnuplot from Python).

もしあなたのGNUPLOTがこれと異なるバージョン番号を表示するときは、そちらに合わせる必要があります。
