Consolidate printf(3) calls at the end of main().

Makes reading the classification algorithm easier.

ok tb@

Use more libm.

adj360() is a modulo operation: use fmod(3) to simplify things.

Adding 0.5 to the phase to steer implicit truncation is a hack:
use lround(3) to simplify things.

Product of a discussion with pjanzen@/jca@/tb@ regarding floating-point
rounding and the importance of correctly classifying a gibbous moon.

ok pjanzen@ jca@ tb@

As we only use the .tv_sec field, simplify gettimeofday(2) -> time(3).

ok tb@ jca@

Remove useless #ifndef in atc(6) and pom(6).

M_PI is always defined, so we can drop those directives.

OK deraadt@, millert@

Callers of time(3) should #include <time.h>.

ok deraadt

Pull in <sys/time.h> for struct timespec, gettimeofday(), clock_gettime(),
and setitimer()

ok deraadt@

- General changes:
- Remove -? from getopt(3) options, but still keep (or add) -h where applicable
- Replace hardcoded program strings by getprogname(3)

- Specific changes:
- atc(6): this used -? and -u for usage(), remove both from game and manpage
- bcd(6): use __progname instead of getprogname(3), no need to include stdlib.h
- hunt(6): replace fputs(3) by fprintf(3)

OK tb@ after his suggestions

Some basic code maintenance in games/

- in main() replace exit with return
- drop some /* NOTREACHED */ lint comments along the way.
- make more use of standard CFLAGS, esp. -Wimplicit-function-declaration
- add and sort some headers when needed
- add straightforward pledges to some programs used at compile time

discussed with and ok mestre@

More cleanup and sorting on header section

OK tb@ and he also pointed out that for consistency with rest of the tree we
should include termios.h instead of sys/ttydefaults.h, where applicable

Set as __dead a few more functions, that don't return, on games/

With precious tip, help and also OK from tb@

Cast isdigit()'s argument to unsigned char.

ok guenther@

Pledge "stdio" for simple games.

ok semarie@

Eliminate use of TM_YEAR_BASE. OK guenther@ deraadt@ miod@

tzfile.h is an internal header that should never have been installed.
What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time. This makes the
tree safe for /usr/include/tzfile.h removal. The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree. Actual removal of tzfile.h is pending
a ports build. Based on a diff from deraadt@

remove superfluous bracket level from time representation.

ok jmc@

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

- use macros for args
- better list -width
- epoch -> Epoch
- missing set of `[]' in usage()

more ansi; khalek@linuxgamers.net

add missing includes
ok deraadt@ tedu@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

No dm -> no need to revoke setegid.

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Use formulae from newer edition of Duffett-Smith's book (and acknowledge in
man page)
Allow command-line selection of dates other than now
Use M_PI
Fix bug occurring just before a new or full moon.

Y2K fix; jsm28@cam.ac.uk

proper gid revoke

setgid games, not setuid games. closes a neat set of holes

From netbsd:
Removed "extern int errno"; Added #include <errno.h> if not already present.
