David, 

I thought I would try out your latest update to try to help out with the compile errors your checkin comments mentioned.  However, I'm seeing some cmake generation errors instead on Windows.  After going through the whole set of checks for the standard header files, it just gives the following messages: 

-- Configuring incomplete, errors occurred!
See also "C:/ORexxDev/oorexx/build/CMakeFiles/CMakeOutput.log".
See also "C:/ORexxDev/oorexx/build/CMakeFiles/CMakeError.log".

The two files are only showing the results for the header file checks with no real error information.  If I comment out the config for the rexx library, this works without error. My first thought was might be some new header file in the checks that needed to be there, but I captured the output from the working case and the failing case, and the check results are identical.  Not sure how to proceed from here.
