Well, I'm currently working on it, it should be a matter of
minutes :-)

The sourceforge web pages are just a dumb copy of the main server. The
ViewCVS script must be able to access CVS repositories directly, and
hence cannot work on source forge (given that our main cvs is on
cvs.freetype.org).

We're switching ftp/web/email servers. However, the current machine
will still hold the cvs repository, and will implement the ViewCVS
itself. The problem should be fixed tonight when everything runs well
and the web updates will have been commited..

Yes, what's worth is that this is the sort of bug that couldn't
have been prevented by using C++, given that the code is using
explicit downcasts based on some assumptions (that were wrong
at that time).

No problem, it'd be hard to write a program that uses all of FreeType's
features anyway :o)
