    This has been discussed many times on the FreeBSD lists.  The FreeBSD
    folks would prefer to simply wait for all architectures to become 64 bits.
    e.g. for IA32 to die out.  I would prefer to make time_t a 64 bit 
    quantity.  But both 'solutions' have serious problems.  time_t is assumed
    to be a 'long' in a great deal of third party code.

    Another alternative would be to create a new 64 bit API or to supply a
    compiler option that allows time_t to be 64 bits for those programs
    that won't barf on 64 bit time_t's.
