This morning I added tzdata1999b to glibc 2.1 and got the following failure when running make check: /usr/glibc/src/buildreport/19990319/timezone/zic -d /usr/glibc/src/buildreport/19990319/timezone/testdata -y ./yearistype asia "asia", line 308: unruly zone "asia", line 308: %s in ruleless zone The problem is: Zone Asia/Nicosia 2:13:28 - LMT 1921 Nov 14 2:00 Cyprus EE%sT 1998 Sep 2:00 EU EE%sT EU isn't defined in asia and EUAsia is used instead.
