The __cxa_guard stuff is part of the Itanium C++ ABI, see
http://refspecs.linuxfoundation.org/cxxabi-1.83.html#once-ctor (or a
slightly newer version at http://www.swag.uwaterloo.ca/asx/ABI.html)

Neither of those is the official version of the doc, but Codesourcery
seem to have moved the page and broken old links to it, and search
engines haven't caught up yet.
