I have an existing body of code using some parts of Boost 1.30 (Bind, Function, Regex, Thread, and some utilities) and compiled using VC++ 7.1 on Windows. I now need to build with g++ 3.3 or 3.4 on Linux as well, and for various reasons I would prefer to use 3.4. Boost 1.30 predates g++ 3.4 by some way and I know that it won't all work without changes. However, neither will 1.31, and 1.32 has still not been released. I would rather not upgrade to either of these in case they break the existing Windows build. Are there any known bugs or other problems in the above-mentioned libraries from Boost 1.30 when used with g++ 3.4, and if so, any known fixes for them? (Assume I'm using Boost 1.30.2 - I might still have 1.30.0 but upgrading to 1.30.2 should be low-risk.) Ben.
