- WARNSify
- getopt returns -1 not EOF
- select() uses an fd_set, not int/long; modify code to use FD_* et al
instead of direct bitwise operations
- in otto.c::look (renamed to ottolook() to prevent name clash), the
case WEST section had a 'goto cont_east', instead of 'goto cont_west'.
(picked up by WARNS=1, because cont_west was an unused label because
of this typo). probably meant that otto got lost in the maze :-/
- deprecate register, convert bcmp() -> memcmp()
