/* Modtime value to use for `infinitely new'. We used to get the current time
from the system and use that whenever we wanted `new'. But that causes
trouble when the machine running make and the machine holding a file have
different ideas about what time it is; and can also lose for `force'
targets, which need to be considered newer than anything that depends on
them, even if said dependents' modtimes are in the future.
NOTE: This assumes 32-bit `time_t's, but I cannot think of a portable way
to produce the largest representable integer of a given signed type. */
