1. If BOOST_NO_EXCEPTIONS is defined, libraries should not throw. One option to implement that behavior is to pass exception objects (of the usual documented library-defined types) to boost::throw_exception.

I wonder how useful supporting exceptions disabled is in recent years? Most recent C++ code assumes throwing exceptions works, and even games consoles which traditionally were very anti exceptions are beginning to weaken on this [1]. I also note that the C++ 11 standard library does a lot more exception throwing than the C++ 03 standard library, so it would surely be harder use C++ 11 with exceptions disabled. All this said, LLVM used to not use exceptions nor RTTI, and could be compiled with both disabled. No idea if this is still the case. Either way it was/is an interesting choice by a large, modern, non-embedded C++ use case. [1]: http://www.gamedev.net/topic/639123-portable-use-and-disabling-of-exceptions Niall
