Added Norman Vine's changes for CYGWIN builds

Added distrules and makerpms for building RPM distributions

Removed old RedHatRPM distribution build directory

Added new dist/RPM directory and placed temporary .spec files (these
are generated by Make/makerpms and are not intended for stand-alone
use, but they keep the directory warm and CVS happy)
