[boost] Serious fix needed for the new Boost.Test

[Maybe I just messed up my XCode #include directories and/or order, or maybe
my CVS is fried....  (After writing the post--) please ignore the first
sentence and excuse any anger instead.]

I've been trying out the auto-test items in Boost.Test, re-doing them when
the recent changes were uploaded to CVS.  I decided to template-ize a test
case I had, going from BOOST_AUTO_TEST_CASE to BOOST_AUTO_TEST_CASE_TEMPLATE
with a MPL list of the types I wanted.  The complier spit out 10 errors.  (I
think that's a lot, but for some posters here that's a little.)  After using
the preprocessor to copy & paste the expansion of
BOOST_AUTO_TEST_CASE_TEMPLATE directly into my test file, I narrowed down
the errors to two actual problems:

1.  The compiler never heard of boost::type
2.  And it never heard of boost::unit_test::ut_detail::
    template_test_case_gen

These can be found in the <boost/type.hpp> (after 10 minutes of searching)
and <boost/test/test_case_template.hpp> (after 30 minutes of searching)
headers, respectively.  Directly #including them in my test file got my
testing to work.

The simple solution is to make sure to _directly_ include the headers for
the items you need to compile....

[Does some checking of the auto-test examples.]

The example for BOOST_AUTO_TEST_CASE_TEMPLATE shows that
<boost/test/test_case_template.hpp> needs to be manually #included.  This is
similar to me having to #include <boost/test/floating_point_comparison.hpp>
in order to make BOOST_CHECK_CLOSE work.  (Is it just me, or does anyone
else find the need to manually add #includes to avoid "missing-item"
compiler errors within the main testing headers _extremely_ annoying?!  I
figure that it saves compiling time if the specialized macro is never used,
and therefore the auxiliary types aren't needed, but is it worth it?)

Well, it seems that I can only complain about the main problem only for
<boost/type.hpp>.  It seems like the author counted on that header being
indirectly #included, and that hope evaporated whenever some other author
purged that header (and boost::type) from his/her library.  So please
directly #include <boost/type.hpp> in <boost/test/unit_test_suite.hpp>.
(And if possible, end the "batteries not #included" scenario for the other
testing macros & headers.)
