Thanks for the hint! I replaced:

    zic_t -> intmax_t
    long -> zic_t
    %ld -> %jd

changed (not necessary but cleaner):

    static const zic_t min_time = INTMAX_MIN;
    static const zic_t max_time = INTMAX_MAX;

and removed unused:

    #define OFFSET_STRLEN_MAXIMUM  (7 + INT_STRLEN_MAXIMUM(long))
    #define RULE_STRLEN_MAXIMUM    8       /* "Mdd.dd.d" */

Tested on both 32 and 64 bit hosts, same zone files produced by the old
and the new zic. No compiler warnings.

Best,
