Hi everyone,

I have difficulties getting c++ compilers (CC, gcc, g++) to compile C++
programs that contain X/Motif resources.  Example:

	I have a C++ program that compiles and run correctly on a DECstation.
	After I add "#include <X11/Intrinsic.h>" (or any other X/Motif-related
	ones) to the source code, all of the above mentioned compilers will give 
	me compilation errors pointing to "Xlib.h".   There is no need to
	actually invoke a function call or use any X/Motif-defined type for
	erros to occur.

There is no problem running C++ program with Motif/X calls in RS/6000, but
problems arise in all the DECstations that I can test on.  These DECs are
running ULTRIX 4.1, and the include files are located in the DEC designated
directories.

Please don't tell me it *should* work.  I tried all I can think of, including
putting "extern" around the include files.  If someone has actually get it to 
work, please help.

Please send your helpful reply to:

P.S. Even the unmodifed source code from Douglas Young choked.  Young wrote a
book on getting C++ to work under Motif.
