[boost] [test] Failing to build on Sun

Now that the Sun regression tests have started up again (with thanks to Noel Belcourt and Sandia), Boost.Test is failing to build on that platform: see http://tinyurl.com/ywm486 for an example but there are probably other errors as well. I wonder if this is as simple as missing the correct includes? Certainly to use ::perror you would need <stdio.h> rather than <cstdio> (as the latter only defines std::perror). I wonder if this is the cause of not finding snprintf as well? Thanks, John.
