just seen a warning I didn't notice before

[Cristian Ionescu-Idbohrn]

Showing up with 'make {menu,old}config':

  HOSTCC  scripts/kconfig/zconf.tab.o
scripts/kconfig/lex.zconf.c:1609: warning: 'input' defined but not used
  HOSTLD  scripts/kconfig/conf

Have no clue as how to sort that out.  May be unimportant.  Still, looking
at the preprocessed code, that point is never reached:

,----
|        static int input (void)
|    {
|     int c;
|
|     *(yy_c_buf_p) = (yy_hold_char);
|
|     if ( *(yy_c_buf_p) == 0 )
|      {
|      if ( (yy_c_buf_p) < &(yy_buffer_stack)[(yy_buffer_stack_top)]->yy_ch_buf[(yy_n_chars)] )
|
|       *(yy_c_buf_p) = '\0';
|
|      else
|       {
|       int offset = (yy_c_buf_p) - (zconftext);
|       ++(yy_c_buf_p);
|
|       switch ( yy_get_next_buffer( ) )
|        {
|        case 2:
|    # 1643 "scripts/kconfig/lex.zconf.c"
|         zconfrestart(zconfin );
|
|        case 1:
|         {
| ->      if ( 1 )
| ->       return (-1);
|
|         if ( ! (yy_did_buffer_switch_on_eof) )
|          zconfrestart(zconfin );
|
| ->      return input();
|         }
|
|        case 0:
|         (yy_c_buf_p) = (zconftext) + offset;
|         break;
|        }
|       }
|      }
|
|     c = *(unsigned char *) (yy_c_buf_p);
|     *(yy_c_buf_p) = '\0';
|     (yy_hold_char) = *++(yy_c_buf_p);
|
|     return c;
|    }
