Package: libc6-dev
Version: 2.2.5-3
Severity: normal
The LSB (well, POSIX) test suite gets its panties in a knot over the
differing values of _POSIX_TZNAME_MAX (6) and sysconf(_SC_TZNAME_MAX)
(which is 3 at least if you run it in a program that hasn't done
anything to cause glibc to change the max). It seems that posix requires
the the sysconf call return a value that is >= _POSIX_TZNAME_MAX.
Given the way glibc changes the later on the fly I can't tell what a
good fix would be, either changing the default value returned by the
sysconf to 6, or changing _POSIX_TZNAME_MAX to 3.
This problem is not debian specific.
