I can take a look at adding some simpler macros that can be called to<br>
initialize code, we take care of all of the defines if CMake is used<br>
but it is quite difficult to get right when not using CMake. Do you<br>
have specific suggestions on how you want to see this fixed Bill? The<br>
errors output indicate the defines are not being set correctly, and<br>
that is why I added the debug output (to make this issue easier to<br>
spot).<br>
