Yet Another Monster Commit: - 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()
