This behaviour seems to be dependent on the Perl version and on
the Win32 "shell" used - the leading whitespace in front of the
1st argument after the program name in the system() call didn't
cause a problem on Windows 98 with ActivePerl 626 (which I used
to develop that part of the Makefile.PL), but it does cause a
problem on other Win32s with different ActivePerl versions.
