adventure(6). The handling of this variable is somewhat confusing,
since it is used for two different purposes (controlling the time
required before a saved game can be restored, and controlling various
aspects of dwarf behaviour); in fact, it is also declared twice in
hdr.h. Except possibly when saving a game fails, these uses can never
interfere; when used for controlling dwarf behaviour, we always have
saved == -1. This can be better understood with reference to the
original PDP-10 FORTRAN source (URL in patch, since hdr.h references
the comments of the FORTRAN as still relevant to this version) of
which the C version is a direct translation: the wrong value for
`saved' meant that someone was cheating and had bypassed normal
initialisation. Saving was done by halting and telling the user to
save their core image, so the question of carrying on after saving
failed to open the output file did not arise.
This patch separates the uses of `saved' into uses of two separate
variables.

use of const I missed in bin/6041; avoiding a signed/unsigned warning;
marking an unused parameter as such; revoking setgid privileges
(including the saved gid) rather than setuid ones; includes and
function prototypes in setup.c; the string passed to err() should not
end with a `.'. Together with the patch sent concerning adventure's
EOF handling, this synchronises adventure(6) in NetBSD with the Linux
port of the NetBSD games.
