System.system fails on windows98se, also disables ghci's :!

as reported and discussed in the thread 
"win98, ctrl-c & System.system (was: Updated 6.4 
Windows installer RC)"
on glasgow-haskell-bugs.

Sigbjorn suggested a fix, getting the command 
interpreter to use from the environment instead of
hardcoding it:

bugs/2005-March/004862.html

note that on my windows98se system, there is no
command.exe, only command.com:

$ echo $COMSPEC
C:\WINDOWS\COMMAND.COM

which does support the /c switch. Btw, I can't find a way 
to pass this switch through System.Cmd.rawSystem - 
can anyone enlighten me on how to do this?

I've fixed this, 6.4.1 should be better (though I can't test
it, so I'd appreciate it if you would test a pre-release
when the time comes).

I can use rawSystem to invoke cmd.exe /c here.  eg. this works:

  rawSystem "c:\\windows\\system32\\cmd.exe" ["/c", "dir"]
