contribute.html: Add bits about getting to the LWG issues pages.

2000-06-19 Benjamin Kosnik <bkoz@soma.redhat.com> * docs/17_intro/contribute.html: Add bits about getting to the LWG issues pages. * 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. * acinclude.m4 (GLIBCPP_CHECK_COMPLEX_MATH_COMPILER_SUPPORT): New. Merge both old compiler bug checks for complex into this.

+<P> NOTE: If using the <TT> --enable-libstdcxx-v3</TT> approach to
+    configuring, the std namespace will be turned on for you, without
+    going this route. Only use this flag if you'd like to experiment with
+    yet more binary incompatibilities, as discussed below.
+</P>
+
 <P>If you build libstdc++ using certain flags (e.g., -fnew-abi), then
    programs that use some of the new C++ language features (like namespace
    std and RTTI) will only link if the compiler's libgcc is built using
