Ugh. Yeah, DOS/Win32 doesn’t have a list of arguments, it only
has a single string.

Each program that wants a list has to parse that flat string
itself. This is, of course, because DOS filenames used to be 8+3,
with many characters disallowed, incl. spaces, so splitting on
spaces was enough, once upon a time.

That’s the kind of brokenness that happens when you try to grow
from toy to serious…

Something like

    open my $child, '-|', join( ' ', map qq["$_"], @cmd )

should work, I think, but I don’t have a Windows box to test
with.
