Can I ask you to please provide some more details as to how you made 
this discovery?

If you do this:

$ cat glw-test.c
#include <Xm/Xm.h>
#include <GL/GLwDrawA.h>
#include <stdio.h>

int main()
{
    printf("glwDrawingAreaWidgetClass %p", glwDrawingAreaWidgetClass);
}

then you could reach that conclusion:

$ gcc glw-test.c ; ./a
glwDrawingAreaWidgetClass 0x0

but this isn't testing correctly as glwDrawingAreaWidgetClass isn't 
marked as extern in GLwDrawA.h

$ cat glw-test.c
#include <Xm/Xm.h>
#include <stdio.h>

extern WidgetClass glwDrawingAreaWidgetClass;

int main()
{
    printf("glwDrawingAreaWidgetClass %p", glwDrawingAreaWidgetClass);
}

$ gcc glw-test.c -lGLw ; ./a
glwDrawingAreaWidgetClass 0x5bd8e3640

I don't know.
