	* include/std/limits (__numeric_limits_base::max_digits10,
	numeric_limits<>::max_digits10, numeric_limits<>::lowest): Add.
	* src/limits.cc: Define max_digits10.
	* config/abi/pre/gnu.ver: Adjust.
	* testsuite/18_support/numeric_limits/dr559.cc: Test max_digits10
	and lowest too.
	* testsuite/18_support/numeric_limits/lowest.cc: New.
	* testsuite/18_support/numeric_limits/max_digits10.cc: New.
