The GCC 4.4.0 release binary for Windows available from http://www.equation.com/servlet/equation.cmd?call=fortran supports std::wstring, std::wcout, etc. Presumably official Cygwin support will follow.
That removes the little remaining incentive I had, so Boost.Filesystem Version 3 will not support BOOST_NO_STD_WSTRING. There had been some previous discussion of this, but it is now definite.
I still don't have an exact target date for V3, but plans should become more concrete over the next couple of months.
Hi Beman, Thanks for proposing a new version of the filesystem library which is very useful. I have tried to run the regression tests with the beta release of cygwin 1.7 but I obtained little success (look at bronf-1.7). I wanted to start testing the wide char thing as they say it is now supported (but only g++ 4.3.2 is currently installed). I suspect something does not work anymore in the testing procedure with the new cygwin but I would need some help to understand what to look for. Nearly all the tests are blank, what does this mean?
