Page 3 of Appendix F of the ALSYS SUN  Users Guide states:
"Values of the following types CANNOT be passed as parameters to 
an external subprogram ...
	-  Private types.

How then, can one use the SAIC Ada binding to XWindows (X11)??
The type DISPLAY is private and used by numerous c subprograms
interfaced via PRAGMA INTERFACE.  Has anyone proven that this
constraint can be disregarded???  Thanks in advance.
