Define in_int32_t_range to check if the 64 bit time_t syscall should be used
Currently glibc uses in_time_t_range to detects time_t overflow, and if it occurs fallbacks to 64 bit syscall version. The function name is confusing because internally time_t might be either 32 bits or 64 bits (depending on __TIMESIZE). This patch refactors the in_time_t_range by replacing it with in_int32_t_range for the case to check if the 64 bit time_t syscall should be used. The in_time_t range is used to detect overflow of the syscall return value. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
