Work around non-compliant gettimeofday on Mac OS X 10.0.4,

(aka Darwin 1.3.7) that caused the date of the first file listed
in long output to be the current time rather than the file's mtime.
The real work is in m4/gettimeofday.m4 and the wrapper function,
lib/gettimeofday.c.

Include gtod.h.
(main): `Call' GETTIMEOFDAY_INIT.
(print_long_format): Add a comment about gettimeofday.
