  * Update the Mac/README file. Add the list of OSX-specific configure options
    to that README file with some explanation.

  * Be more strict in the configure script: complain loudly when the user has
    specified invalid combinations of OSX-specific configure arguments.

    The error message refers to the Mac/README file for more information.
