configure:

checking for 64-bit time_t... no
configure: WARNING: This package requires a 64-bit 'time_t' type if there is any way to access timestamps outside the year range 1901-2038 on your platform. Perhaps you should configure with 'CPPFLAGS="-m64" LDFLAGS="-m64"'?

https://github.com/jaykrell/cm3/blob/master/m3-libs/m3core/src/m3core.h
suggests how:

#ifdef __osf__
/* Request 64bit time_t. Not available on v4. Would be good to autoconf this.
 * We later check for TIMEVAL64TO32/TIMEVAL32TO64 to see if this works.
 */
#ifndef _TIME64_T
#define _TIME64_T
#endif
#endif /* osf */

.
.
.

#include <sys/time.h>

/* Check if this system really supports _TIME64_T, i.e. Tru64 v5.1 or later. */
#if defined(_TIME64_T) && !defined(TIMEVAL64TO32) && !defined(TIMEVAL32TO64)
#undef _TIME64_T
#endif

Thank you,
