I’d like to test 5.2, and I don’t want to un-install 4.8.4 because it works with our current code base. I know that 4.9.0 had problems with our code and so I might want to re-try that with the latest version. My major question is in the subject: Can I install both at the same time? I know that

Re: Problem with gcc4.7 and call_once

So why does building the code from scratch with the --enable-libstdcxx-threads flag work, and not when using the port or when the port file configuration adds that option? Jeremy has shown that the MP version does not work for std::call_once, and gcc.org has results showing that it works fine
