sysconf(_SC_TZNAME_MAX)

[Thorsten Kukuk]

Hi,

the AustinDraft writes about TZNAME_MAX:

Maximum number of bytes supported for the name of a timezone (not of the TZ variable).
Minimum Acceptable Value: {_POSIX_TZNAME_MAX}

Our return value of sysconf(_SC_TZNAME_MAX) is wrong, we return 4,
but _POSIX_TZNAME_MAX is defined as 6. if __tzname_max is less than
this, we should return _POSIX_TZNAME_MAX. I propose the following 
patch to fix this:

	* time/tzset.c(__tzname_max): Return at least _POSIX_TZNAME_MAX.
