Why use BOOST_THROW_EXCEPTION to throw?
- Typically, there is no need to do anything else to support BOOST_NO_EXCEPTIONS builds;
- Enables boost::exception_ptr, so the exceptions you throw can be transported between threads;
- Enables boost::error_info, so users can attach stuff to exceptions.
- Enables better messages from boost::diagnostic_information.

What about boost/detail/no_exceptions_support.hpp? Could that file be moved to boost/exception for public use? I use it, but don't feel comfortable with it being in the detail directory.
This header is news to me. :) Maybe something like this could become a documented part of Boost Exception.
I don't understand why the macros defined in no_exceptions_support.hpp expand to if("") { } else if(!"") { } etc. in BOOST_NO_EXCEPTIONS builds. Expanding to if(true) { } else if(false) { } seems more appropriate to me.
It seems that there were some issues with Borland # if BOOST_WORKAROUND(__BORLANDC__, BOOST_TESTED_AT(0x564)) # define BOOST_TRY { if ("") # define BOOST_CATCH(x) else if (!"") # else # define BOOST_TRY { if (true) # define BOOST_CATCH(x) else if (false) # endif Best, Vicente
