        * configure.in (targetfile): Ignore TM_FILE, don't just issue
        warning.
        (tm_h, xm_h, nm_h, GDB_TM_FILE, GDB_XM_FILE, GDB_NM_FILE): Define.
        * acconfig.h (GDB_XM_FILE, GDB_TM_FILE, GDB_NM_FILE): Add.
        * config/nm-empty.h: Delete.
        * defs.h (xm.h, nm.h, tm.h): Only include when GDB_XM_FILE,
        GDB_NM_FILE or GDB_TM_FILE defined.
        * Makefile.in (defs_h): Replace tm.h, xm.h and nm.h with tm_h,
        xm_h and nm_h macro that are defined by configure.
        (tm_h, xm_h, tm_h): New.
        * configure, config.in: Regenerate
        * TODO: Update.
