acinclude.m4 ([GLIBCXX_ENABLE_VISIBILITY]): Rename to [GLIBCXX_ENABLE_LIBSTDCXX_VISIBILITY]... 

2011-11-08  Paolo Carlini  <paolo.carlini@oracle.com>

	* acinclude.m4 ([GLIBCXX_ENABLE_VISIBILITY]): Rename to
	[GLIBCXX_ENABLE_LIBSTDCXX_VISIBILITY], likewise for the
	option itself, to --enable-libstdcxx-visibility.
	* configure.ac: Adjust call.
