+1.4 Improvements to the build system for the Cygwin case
+
+The Cygwin platform provides a full-featured Unix environment on
+Windows.  CMake has recently been changed (at the request of Cygwin
+developers) to emphasize the Unix aspects of the Cygwin platform and
+deemphasize the Windows aspects of that platform.  It was argued this
+change would tend to make CMake builds of software much more reliable
+on Cygwin, and after some small but important changes to our
+CMake-based build system to adjust for these recent CMake changes for
+Cygwin, we have indeed confirmed that prediction for the PLplot case.
+There are still some Cygwin platform issues left which are being
+discussed on our Wiki at http://www.miscdebris.net/plplot_wiki/, but
+some fundamental breakthroughs have also been made for the Cygwin case
+that should interest all our Windows users.  For example, for the
+first time ever we have been able to build our cairo and qt device
+drivers on the Cygwin platform giving our Windows users convenient
+access to the many high-quality PLplot devices that are available with
+these two different device drivers.
