The mingw Windows script has been updated, it will compile the latest svn now. You need to give it a completely fresh start, however (delete the stuff from previous scripts).

I'm officially dropping Visual C++ support on Windows now, in terms of documentation. I will keep using it for debugging, but the build process has gotten too complex (and painful), and keeping the build doc updated would require more work than it's worth. In terms of GPL compliance, mingw is the better choice anyway.

> 2007-12-13 0.6-final, this is the same as 1452 ?

No, 1452 is a development revision.
