  Set the default size of time_t_bits to match the standard runtimes. The
size must match that which is used in the VSB, since the same VSB is
used to build all of the runtimes.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* libgnat/s-parame__ae653.ads (time_t_bits): Change to
	Long_Long_Integer'Size.  Add some comments to explain.
