r12754: - sync TIME_T_MAX calculation from samba3
- but limit TIME_T_MAX to INT32_MAX, otherwise 64 platfroms are broken because gmtime() will fail with INT64_MAX passed in! I'm not sure if that's the best fix for this problem, but it works... Should we port the INT32_MAX limitation to samba3? Comments, please? metze (This used to be commit 396fa81be5b950aa2120cff19540a0236f79a685)
