mknumeric_limits (trait_name): Fix copyright notice.

2000-04-30  Benjamin Kosnik  <bkoz@gnu.org>

	* mknumeric_limits (trait_name): Fix copyright notice.
	* src/gen-num-limits.cc: Explicitly instantiate epsilon and
	round_error data members of struct value. This works around
	weak-linking issues on AIX, HPUX.
