Done.

	* acinclude.m4 (GLIBCPP_CHECK_LINKER_FEATURES): Do not clear
	SECTION_LDFLAGS and OPT_LDFLAGS.  Fix ac_sectionLDflags type.
	* aclocal.m4: Regenerate.
	* configure: Regenerate.
	

> 	Can you or one of the main V3 developers apply the acinclude.m4
> patch?  I don't have the right version of Autoconf to rebuild the files.
