Now, disable cmd.exe on the windows system
and run the test again.

The idea is an SPP that uses PowerShell to
function and can operate on a system without
cmd.exe, command.com, or batch files.

The problem is SPP doesn't run without
cmd.exe and batch file support on a PC.

The goal is to be able to use a native
windows perl (SPP) when only PowerShell
is available.  ATM, cygwin perl is an option
for these conditions but the emulation of
POSIX makes for a bit of a performance hit.
