Taglib in 64bit on OS X 10.6?

I've been compiling and using TagLib as a 32/64 bit universal
framework for a while, and haven't had too many issues. There are
quite a few implicit 64-to-32 bit conversion warnings when compiling,
and the TAGLIB_IGNORE_MISSING_DESTRUCTOR pragma does not work with
LLVM so warnings are emitted about non-virtual destructors.  I also
receive the occasional crash report originating in TagLib that I
haven't been able to narrow down.

I'm happy to share the .xcodeproj files if anyone is interested.
