than embedding a copy. Discussed upstream but was not desired.
History:
-r10 : make timezone case insensitive
+r12: adapt for upstream changes for new zic
+r11: use canonical names to avoid more case sensitivity issues
+ round lat/long from zone.tab towards zero per builtin db
+r10: make timezone case insensitive
r9: fix another compile error without --with-system-tzdata configured (Michael Heimpold)
r8: fix compile error without --with-system-tzdata configured
r7: improve check for valid timezone id to exclude directories
-r6: fix fd leak in r5, fix country code/BC flag use in
+r6: fix fd leak in r5, fix country code/BC flag use in
timezone_identifiers_list() using system db,
fix use of PECL timezonedb to override system db,
r5: reverts addition of "System/Localtime" fake tzname.
r2: add filesystem trawl to set up name alias index
r1: initial revision
