Dear all, when looking at Boost as a whole its obvious that it uses C++ exceptions to report exceptional conditions because its the C++ way of doing it and it has to interact with the C++ standard library. On the other hand it seems also obvious that some libraries (Boost.Units, Boost.MPL, etc.) do probably not use C++ exceptions at all since they are pure compile time libraries or provide services which do not have exceptional cases. I am working on a C++ based project which forbids the usage of C++ exceptions but it is still preferable to use Boost libraries at least the ones which do not make use of C++ exceptions at all. I am especially interested in using Boost.Units and Boost.Math. Which of Boost libraries do NOT make use of C++ exceptions (i did not find such a list but maybe its already available somewhere)? What would it take to use these libraries as a stand-alone "minimal" Boost library? Thanks
