[gambit-list] shell-command question (v4.7.3)

[Ryuho Yokoyama]

Hello,

I am a very satisfied Gambit user. (prebuilt/gambc-v4_6_0-windows-mingw.exe)
Now I wont to use latest version.  (prebuilt/gambc-v4_7_3-windows-mingw32.exe)
                                                       (prebuilt/gambc-v4_7_3-windows-mingw64.exe)
                            
But I can not use latest version of shell-command as below.
