tzcode94b.tar.gz and tzdata94b.tar.gz

[Arthur David Olson]

Updated time zone code and data is available by anonymous ftp from
elsie.nci.nih.gov (128.231.16.1) in the "pub" directory; the culprits are

	-rw-r--r--  1 ado         62145 Feb  7 10:04 tzcode94b.tar.gz
	-rw-r--r--  1 ado         63993 Feb  7 10:04 tzdata94b.tar.gz

The updates are the work by Paul Eggert (eggert at twinsun.com) who notes:

> I found another book of time zone histories by E W Whitman; it's not as
> extensive as Shanks but has a few goodies of its own.  I used it to
> update the tables.  I also fixed some more as a result of
> correspondence with Adam David and Peter Ilieve, and move some stray
> links from `europe' to `backward'.  I corrected some scanning errors in
> usno1989.
> 
> As far as the code goes, I fixed zic to allow years in the range
> INT_MIN to INT_MAX; this fixed a few boundary conditions around 1900.
> And I cleaned up the zic documentation a little bit.
