When I link a X program that I wrote on a SunOS 4.0.3 or 4.1 machine I get the 
error "ld.so: symbol not found _XtInherit".

	What you are seeing is a side-effect of a kludge in the R4 libXt.a to 
get Sun shared libraries working.  Apparently, you can't share a function that 
is both called and compared, as _XtInherit is. This was handled by putting 
_XtInherit in the same file as a function that is always used, thereby 
guaranteeing that it would be loaded -- that is, in Initialize.c, where 
XtToolkitInitialize() and XtInitialize() reside. These routines would normally
be called.

	You are probably seeing this error because your program is not a normal
Xt-based program and does not call XtToolkitInitialize() anywhere. 
	1) it may be a program that uses Xt functions but never opens a 
connection to the X server.  [OSF/Motif's 1.1.0 UIL had this problem; it called
XtMalloc() and other Xt functions.] The solution is to add the call to your 
program; the function does not have to be executed, just linked in.
	2) alternatively, your program doesn't need any Xt functions and is
correct in not calling XtToolkitInitialize() -- it may be an Xlib or XView 
program. In this case, you can remove -lXt from your link command. 

	It should not be necessary to link the shared libraries statically,
although this will certainly solve the problem.

You may also see this error compiling X11R5 programs on a SunOS 4.1.3 machine;
be sure to set OSTeenyVersion to 3 in the config/sun.cf file.
