Problem with the threadsafe programm.

[abdelaziz boushabi]

Hello,
            I am doing a work experience at Opteway and I am following
your work
about time zone. I am also working about the threadsafe version and I
noticed some problems.

    The problem :
            when I use the "tz_prep" function of the library "libtz.a",
it indicates me an error.
This function works correctly on Linux but doesn't work neither on SunOS
nor on Tru64.

    Thank you for your attention.
