Both intprops.h and TIME_T_MAX seem massively over-engineered for the
present bug; neither the buffer overrun, not the build failure, nor
handling of out-of-range u_long values should need a 500-line patch.
Since time_t is always at least as wide as long in glibc, "clock < 0" is
entirely sufficient to detect the case of a u_long value that does not fit
in time_t.
