Merge the latest unordered changes. These are concerned with getting the tests

working on more compilers. The biggest change is that the exception tests have
been changed to use a very simple exception testing mechanism on top of
lightweight_test. This was because Boost.Test exception testing isn't working
on several platforms. I'm trying to set this up so that I can use Boost.Test on
compilers which it completely supports, and lightweight test on others.
Boost.Test tests more than my simple exception testing code ever will so it's
worth using where I can.
