Also later:

     [..]  It also lets writers not
     supporting obsolescent readers use a tzh_timecnt of zero in the version 1
     data block to save space.

and we switched to non "-b fat" (see zic(8)) files for netbsd-9:

     -b bloat    Output backward-compatibility data as specified by bloat.  If
                 bloat is fat, generate additional data entries that work
                 around potential bugs or incompatibilities in older software,
                 such as software that mishandles the 64-bit generated data.
                 If bloat is slim, keep the output files small; this can help
                 check for the bugs and incompatibilities.  The default is
                 slim, as software that mishandles 64-bit data typically Also
                 see the -r option for another way to alter output size.

But overall: clearly a bug in gnustep, version 1 format files are obsolete.
