[boost] [important] Preparing to Test Release Builds

In order to make it viable to do boost-wide regression testing in release mode, I've gone through all the instances of assert() in our libs subdirectories and replaced any that seemed to be used for testing with constructs that don't get compiled away in release builds. This affects the following libraries: boost/cast.hpp mpl conversion function functional graph iterator mpl parameter program_options ptr_container python spirit If you maintain one of these libraries please review the attached patch, which I plan to apply on Wednesday unless there are objections. -- Dave Abrahams Boost Consulting www.boost-consulting.com
