Forwards slashes are allowed under the UNC, but generally not used on
Windows since many programs use forward slash for command line options.

I have added:

   If Unix style paths occur, replace them with a Windows style path
   that conforms to the Windows Uniform Naming Convention (UNC), for
   example:

         MERCURY_ERLANG_COMPILER=/c/Program\ Files/erl5.8.2/bin/erlc

    should be replaced with:

         MERCURY_ERLANG_COMPILER=C:\Program Files\erl5.8.2\bin\erlc

I don't think so.  I will check before I commit though.
