I wonder how much work it would be to fix the cygwin dll?

Maybe we should either badger the Cygwin folks, or contribute patches. It 
certainly is a bother not to have wide character support.

In the meantime, I've disabled i18n wide character support in 
Boost.Filesystem for older broken compilers, and any library without locale 
or wstring support.
