Problems when mounting c: to /

Hallo everybody! When installing ghc-4.08.2 (onWinNT) as described in the installation instructions under c:, I couldn't get ghc to run. It invoked the C-preprozessor and stoped after cleaning. When I unmount c:, it works fine. (If I install cygwin and dont mount c: to / it works fine too.) But now //c/ is the normal win-root. That's not a problem for me, but how about ghc? Does it depend in any way on c: mounted to /? If not why do you want this mount (in the installation instructions section 2.2.2.1)? Thanks, Andreas PS: Thanks Reuben for the new install shield and a very big thanks to all of you who have their parts in getting the profiling to run under WinNT
