It was probably the lexical_cast update. I see that Boost.Test uses it (the
unit_test_parameters.ipp file). This presents something of a chicken-and-egg
situation for lexical_cast, as its test also uses Boost.Test...

However, I took a snapshot of the regression test result prior to the
update, and even then, the lexical_cast test failed on gcc-2.95.3 (I don't
have the linked-to pages showing the errors, though. We don't happen to have
historical regression test results available somewhere?), so when it failed
after the update, I thought it was the same problem. In the future, I'll
make sure to note any regression test _error messages_ also, before
updating.

I see that it on both tests fail on this line in lexical_cast:

/boost/head-regression/boost/boost/lexical_cast.hpp:157: parse error before
`>'

                       stream.get() == std::char_traits<char_type>::eof();

Any idea how to detect gcc-2.95.3's problem, so we may revert to the
original code for that one? (the above code ensures there aren't any
whitespace left after a conversion)
