* doc/invoke.texi (C++ Dialect Options): Note that
	-fvisibility-inlines-hidden doesn't affect explicitly
	instantiationed inline methods.

cp:
	* decl2.c (determine_visibility_from_class): Don't use hidden
	visibility for explicit instantiations.

testsuite:
	* g++.dg/ext/visibility/fvisibility-inlines-hidden-3.C: New test.
