Can you replace it with

  #undef HAVE_XDBE

then edit src/Makefile to make the XDBE-related variables empty, like
this:

  XDBE_LIBS =
  XDBE_CFLAGS =

and then rebuild Emacs and see if the problem persists.

Alternatively, temporarily rename the header X11/extensions/Xdbe.h in
your include directory to something else, then re-run 'configure' and
rebuild.
