I've added the line into my config.h and now there is no difference
between pressing BackSpace and Alt+Backspace. I don't remove this line.

{ XK_BackSpace, XK_NO_MOD, "\177", 0, 0, 0},

$ showkey -a

Press any keys - Ctrl-D will terminate this program

^? 127 0177 0x7f
^? 127 0177 0x7f

The first ^? is BackSpace pressed, the second ^? is Alt+Backspace pressed.
Should I add "\033\177" or there is another workaround?

For additional information, urxvt recognizes alt+BackSpace perfectly.
^[^? 27 0033 0x1b
