These symbols were removed from the X Server, or never declared.
  One symbol that may need special attention is XkbBuildCoreState(),
that doesn't have a prototype anywhere, but is called from
xkb/xkbEvents.c:XkbFilterEvents(), and also used by the macros
XkbStateFieldFromRec() and XkbGrabStateFromRec() defined in
include/xkbstr.h.
  fb/wfbrename.h also may need some cleanup, as it makes several
"renames" of non existing symbols.
