That chunk probably shouldn't be in the win32 code ;-)  A: we should fix 
the PERL5LIB problem and  B: I don't think that kernel has the same 
error message as redhat.

As for the rest, it's possible that we're just as well to do the quoting 
and run system($scalar) here, but we could possibly still keep it as a 
list.  I think win32/win32.c implies that it does get to the win32 api 
as a list, but I'm not sure.

  system($^X, '-e', '"print \\"hello world!\n\\""');

So if it has ", then it has to be wrapped in ", and then any " have to 
be \", but also any literal \ preceding a " needs to become \\\".

Thanks,
Eric
