e3b218cd7b Add a check for wtmp records which have invalid values for ut_time. Wtmp
records with time==0 get "the time of the last valid record", while records
where time goes backwards (compared to the previous record) are skipped.
Also prints a message saying how many records were changed or skipped due
to these checks. Check was inspired by a simpler check in OpenBSD's version.

This is all meant to sidestep problems that Tillman Hodgson noticed with 'ac'
when running sparc64 with 64-bit time_t's.  The real problem is whatever is
creating wtmp records with ut_time==0, of course, but I have not yet figured
out what is doing that.

b5a06c256e Add a debug-statement from NetBSD, and then rework all debug-statements
so the program compiles without errors or warnings when DEBUG is defined on
sparc64 with 64-bit time_t's.  Also have debug statements include the year
when printing records from a different year than 'now'.  Also print out a
special timestamp in debug statements when ut_time==0.

7f761c522e Convert K&R-style routine definitions to C89 style, partially to reduce
diffs with OpenBSD.  This causes no changes to the object produced.

db774d6099 Fixed some world breakage caused by not updating clients when <timeconv.h>
was split off from <time.h>.  This became fatal here when -Werror was
reenabled.

170ac683f2 I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions.  e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard.  They will eventually be replaced when a real standard
comes out of committee.

1ce46cef12 /var/log/wtmp entries for ptys are treated differently in ac, since
they may not be logins.  The code for determining whether it is a pty
entry is broken.
