I no longer have access to 2.5, but I do have 2.5.1 and 2.6, and have
verified that they have the bug.  But I now see that I gave you a
oversimplified version of the problem, as you have to have a tzset
that does real work.  Here's a test case that illustrates the bug; it
fails on Solaris 2.5.1 and 2.6.  I'm reluctant to use memcmp in the
test case since I worry it might mishandle tm_* members other than the
ones required by the standard.

#include <time.h>
#include <stdlib.h>

int
main ()
{
  time_t t1 = 853958121;
  struct tm *p, s;
  putenv ("TZ=GMT0");
  p = localtime (&t1);
  s = *p;
  putenv ("TZ=EST+3EDT+2,M10.1.0/00:00:00,M2.3.0/00:00:00");
  tzset ();
  exit (p->tm_year != s.tm_year
        || p->tm_mon != s.tm_mon
        || p->tm_mday != s.tm_mday
        || p->tm_hour != s.tm_hour
        || p->tm_min != s.tm_min
        || p->tm_sec != s.tm_sec);
}
