I want to detect whether or not the -no_exception compile time flag has been used on gcc/clang. Will BOOST_NO_EXCEPTIONS do this? If not is there something I can use?

A look at the code or a simple Google search allows to answer these questions. Boost.Config will define BOOST_NO_EXCEPTIONS if it is not already defined and it detects that the compiler has exceptions disabled.

I couldn't see this from looking at the implementation in config.hpp. Maybe I missed it. I think that config.hpp will detect if the compiler doesn't support exceptions. But it doesn't look that it detects when the exceptions are suppressed via the -no-exceptions switch.
