Tidy up the $hardtop test:

  - use cygpath -m to calculate $hardtop on Windows, rather than
    our own partial solution.  Fixes building under c:/cygwin
    on Windows.

  - remove some old stuff dealing with paths we used to use at
    Glasgow.

  - use proper AC_MSG macros instead of explicit echo.
