[libdispatch-dev] Updates regarding the status of libdispatch on Windows

I am very glad to report good news on the topic libdispatch on windows.
Yesterday we managed to eradicate the last obvious bugs and all tests
and can now completely build and run libdispatch by using MSVC (Visual
Studio 2010) on windows. All tests seem to pass or fail the same way
they currently do on Linux, so at least we have reached feature parity
;) - Please see the test results attached [1], the responsible code can
be found at http://opensource.mlba-team.de/svn/xdispatch/tags/0.4/ (see
the core folder for the libdispatch implementation).
The big question to raise now is wether merging back to macosforge.org
is possible or not. We had to change a lot of the sources and some of
the changes do not really contribute to the maintainability of the code,
e.g. MSVC still does not support named intializers in structs.
Additionally I split queue.c into several subfiles, such as debug.c and
so on, to make the different implementations for the different platforms
easier to find. As such it will be quite difficult to provide small
patches instead of one or two bigger ones. And there is DrPizza/Peter's
port as well, although I do not know how much of his work is tested.
What do you think about it?
