% requested (major,minor,point) version, e.g., to test for a MacOS/X system
% of 10.4.8 or later, do a IsMinimumOSXVersion(10,4,8);
%
% rc is 0 if the system is of a lower version, 1 if it satisfies this
% minimum version, 2 if the function doesn't know.
% History:
% 11/26/2007 Written (MK), based on code by Roger Woods (UCLA).
% 05/28/2012 Fixed this bullshit (MK).
% 11/01/2014 Convert to do without use of deprecated Gestalt() (MK).
