std_limits.h: Move static const data members out of generic template...

2002-03-08  Benjamin Kosnik  <bkoz@redhat.com>

	* include/std/std_limits.h: Move static const data members out of
	generic template, into base class __numeric_limits_base.
	* src/limits.cc: Add definitions.
	* config/linker-map.gnu: Add __numeric_limits_base.
	* testsuite/18_support/numeric_limits.cc: Declare test in scope.
