from a 32-bit value to a 64-bit value. This commit does not actually change anything. It merely provides instructions, scripts, and a safety measure in Makefile.inc1 for people who want to make the change. The real change to 64-bit time_t's on sparc64 is scheduled to happen on March 10th, assuming that so major problems are found between now and then by early-adopters. Reviewed by: freebsd-sparc64
