	* docs/documentation.html: Rename link to make more accurate and scary.
	* docs/gccrebuild.html: Edit for clarity as these are no longer
	separate projects.
	* docs/install.html: Add bits about binutils for
	-ffunction-sections, -fdata-sections, -Wl,--gc-sections

	* configure.in: Add call for GLIBCPP_CHECK_COMPLEX_MATH_SUPPORT.
	* math/Makefile.am (EXTRA_DIST): Change USE_LONG_DOUBLE to
	USE_COMPLEX_LONG_DOUBLE.
	* acinclude.m4 (GLIBCPP_CHECK_MATH_SUPPORT): Break into
	GLIBCPP_CHECK_MATH_SUPPORT and GLIBCPP_CHECK_COMPLEX_MATH_SUPPORT.
	Works around irregularies in powerpc "C" compiler, but a good idea
	anyway.

	New. Merge both old compiler bug checks for complex into this.
