<li>If you intend to work on Clang C++ support, you may need to tell it how
to find your C++ standard library headers. If Clang cannot find your
system libstdc++ headers, please follow these instructions:
<ul>
<li>'<tt>gcc -v -x c++ /dev/null -fsyntax-only</tt>' to get the
path.</li>
<li>Look for the comment "FIXME: temporary hack:
hard-coded paths" in <tt>clang/lib/Frontend/InitHeaderSearch.cpp</tt> and
change the lines below to include that path.</li>
</ul>
to find your C++ standard library headers. In general, Clang will detect
the best version of libstdc++ headers available and use them - it will
look both for system installations of libstdc++ as well as installations
adjacent to Clang itself. If your configuration fits neither of these
scenarios, you can use the <tt>--with-gcc-toolchain</tt> configure option
to tell Clang where the gcc containing the desired libstdc++ is installed.
