+       * Makefile.in (X11_INCLUDES): Define as empty.
+       (X11_CFLAGS): Define as including $(X11_INCLUDES).
+       (X11_LIB_SWITCHES): Define as empty.
+       (X11_LIBS): Define as -lX11.
+
+       * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
+       and --x-libraries switches, setting the X11_INCLUDES and
+       X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
+       in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
+
+       * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
+       it.  This means that the stop button doesn't work, but is better
+       than nothing.

        * mips-tdep.c (mips_print_register): Remove unused variable
