I'm just guessing, but this smells to me like a problem with largefile-
vs-not-largefile support.  We discovered long ago that when pg_config.h
defines _FILE_OFFSET_BITS or _LARGEFILE_SOURCE, it's critical that the
compiler see that *before* it includes stdio.h.  Unfortunately it seems
this hard-won knowledge didn't get propagated into tsearch2 until just
recently :-(.  Try applying the tsearch2 changes linked here:
http://archives.postgresql.org/pgsql-committers/2005-05/msg00068.php
and let us know if that helps.  I have not back-patched these changes
into existing release branches, but if it turns out to address a real
problem-seen-in-the-field then that should get done ...
