The problem was with the program, not the compile-line.  I've included the
modified version below; it will compile and run on a SPARC Station 1 running
Sun OS 4.0.3c using GNU's g++ and X11R4.

The compile line was:

g++ junk.c -lXaw -lXmu -lXt -lXext -lX11


You might want to think about either using the extern "C" {} declaration for
the X headers or making sure that they're all modified to be C++ compatible.

----------------------------  junk.c -------------------------------------

#include <stdio.h>
#include <X11/Intrinsic.h>    
#include <X11/Xaw/Label.h>    
#include <X11/Xaw/Cardinals.h>    

String fallback_resources[] = { "*Label.Label:    This is xlabel", NULL };
 
static XrmOptionDescRec options[] = {
{"-label",    "*Label.label",    XrmoptionSepArg,    NULL}
};

main(int argc, char** argv)
{
    static void Syntax();
    XtAppContext app_con;
    Widget toplevel;

    toplevel = XtAppInitialize(&app_con, "Xlabel", options, XtNumber(options),
                   &argc, argv, fallback_resources, NULL, ZERO);

    (void) XtCreateManagedWidget("label", labelWidgetClass, toplevel, 
                 NULL, ZERO);
    XtRealizeWidget(toplevel);
    XtAppMainLoop(app_con);
}
