The files
	zic.c zdump.c tzfile.h private.h tzselect.ksh version
come from the tzcode package by Arthur David Olson et.al.
The 'version' file specifies which tzcode version was used.

The files
	africa antarctica asia australasia europe
	northamerica southamerica pacificnew etcetera factory
	backward systemv solar87 solar88 solar89
	iso3166.tab zone.tab leapseconds yearistype
come from the tzdata package by Arthur David Olson et.al.
except that its 'yearistype.sh' file is renamed to 'yearistype'.
These tzdata files were taken from tzdata 2009i and have not been
updated since, as they do not affect glibc installation and are
present only for regression testing.
