echo is a builtin command of command.com on Win9x and cmd.exe on
NT4/W2K, so you can't just call it with the system command.
In a bash window the situation is different - even though echo is a
shell builtin, the calling bash can run it. Besides that, there is an
external program named echo.exe, too.
If you want to test your program use something like "notepad", which can
be found through $PATH on all WinXX systems.
