[boost] Added new test file, need help testing

I added another test file for the I/O-state saving classes.  It's in 
the main Boost CVS as "boost/libs/io/test/ios_state_unit_test.cpp".

I have two compilers installed (GCC 3.1 and CodeWarrior 8).  I wrote 
and tested the new file with CodeWarrior.  But my GCC doesn't support 
the wchar_t part of the libraries, so I can't test with that compiler.  
Can other people test the file with other compilers to make sure 
everything is OK?

I want the new file to replace the current test file there, but I want 
to make sure everything works.

For locale experts and Metrowerks engineers: the unit test for the 
locale saving class has big comments about a problem with use_facet.  
Some book I got on IOStreams says that use_facet should do an ID check 
and a dynamic_cast check, but the CodeWarrior implementation seems to 
only do the ID check.  Should CodeWarrior change to also do the 
dynamic-check?  The standard is vague on this question.  (It could just 
be a QoI issue; maybe there's a DR on it.)
