Works for me! Remember that System.system is executing CMD.EXE, not
Cygwin bash, so it'll probably have a different PATH and might not be
able to find your Cygwin binaries. Both System.system "dir", and
System.system "c:/cygwin/bin/ls" work for me.
There's no such thing as cmd.exe on Win9x, it's COMMAND.EXE/COM.
Some System.Process.* code ought to be looking at the COMSPEC env
variable and not hard-code the name of the command processor. However,
I don't think COMMAND.EXE supports the /c switch...why the switch away
from just using libc/msvcrt's system() for System.system?
