(just curious) Is it because of C++ ABI changes? Fortunately, the ABI remains compatible (partly due to a few nips & tucks from our compiler team). Gcc4.0 is much more strict about C++ and disallows several things that were allowed (though warned about) in gcc3.3. This particular build failure was due to an illegal cast from a method to a function pointer. We added the function OSMemberFunctionCast() in libkern/c++/OSMetaClass.h to handle this cast safely, but we didn't get around to using it everywhere yet.

It seems rather overbearing of xnu to require the developer to switch their default compiler (might be building other stuff too...) Perhaps, but I think you'll find that most of the Darwin projects expect to be built with gcc3.3. This email sent to site_archiver@lists.apple.com
