David Leverton writes about adventure/crc.c:

The 'adventure' game from the games-misc/bsd-games-2.13 package crashes
when saving the game on AMD64 (and probably other 64-bit systems, but I
haven't checked).  Find attached to fix this.

About utmpentry.c:

the utmpx structure defines the ut_tv member a little differently on
64bit hosts so that a 32bit and 64bit structure can be shared.  So the
ut_tv is a custom 32bit structure rather than the native 64bit timeval
structure.  Work around is to assign the submembers instead.
