Hi, Friends:

 When I was compiling edd/dm with EPICS3.12.2,  I got a compiler error related
to X-window's Graphic context structure.  Some routines access access
directly "value" field of GC structure.  Compiler claims that there is NOT
such field. Sure enough, /usr/include/X11R4/X11/Xlib.h file on  
our machine (HP-UX 9.05) defines GC as follows:

typedef struct _XGC
#ifdef XLIB_ILLEGAL_ACCESS
{
    XExtData *ext_data;	/* hook for extension to hang data */
    GContext gid;	/* protocol ID for graphics context */
    /* there is more to this structure, but it is private to Xlib */
}
#endif
*GC;

Although I could build edd/dm with MIT version of X11R5, I'm wondering 
if GC->value field is still in X11R6?

PS: The most(Not ALL)  of direct use of value field and its contents can be 
replaced by XGetGCValues routine.
