(1) By default you will be building and installing the libraries in
     around nine different grades.  If you don't need them all, try
     disabling some of them (see ./configure --help for the options used
     to set the grades to be installed.)

(2) The added overhead of running under cygwin.

Have you looked in README.MinGW?  (Note that you can also build Mercury
using MYSYS - the MinGW shell.)
