There seems to be a problem with the "system LIST" command on Win32.

The following 1-line test program

  system "$^X -e \"print 1\"";

correctly prints a "1".

The (supposedly equivalent)

  system $^X, "-e", "print 1";

prints nothing.

There seems to be a problem with the "system LIST" command on Win32.

The following 1-line test program

 system "$^X \-e \\"print 1\\"";

correctly prints a "1".

The (supposedly equivalent)

 system $^X\, "\-e"\, "print 1";

prints nothing.

Thanks for the reminder. The problem is still outstanding in 5.6.0. As I
understand it, this requires a fairly significant reorganisation of the
internals of system/exec for Win32 (reflecting the fact that on Windows,
executing a command line is the fundamental operation, as opposed to Unix
where executing an argv array is the fundamental operation).

When I raised the bug, I looked at what would be involved in fixing it, but
it's beyond my capabilities/available time.

I believe that this bug should remain open.

Paul.
