I have to reply to this:
Despite the inherit differences between X-windows and ms-windows,
we have found that we can use the one set of source code for ms-win
and x-windows.
We use the F45genm tool to regenerate for x-windows the source code
which we designed and developed for and under ms-windows.
The changes required were trivial - basically we had to change the
routine we were using for sizing our windows to check for the
operating system (get_application_system(operating_system)) and
do it based on that.
This allows us to maintain ONE set of source for both OS.
We have been very happy with the result.
