Lack of Cygwin/GCC/g++ C++ standard library support for wide strings and 
streams causes me enough grief that I'd willing to round up some Boost 
folks to contribute any of these missing functions that are required. 
But I'd really prefer a mentor familiar with Cygwin's and Newlib's needs 
and requirements to provide a bit of guidance and make sure we don't 
spin our wheels too much while getting started.

Any interest?
