--------------------------+-------------------------------------------------
The attached patches, (in-?)conveniently separated by affected file, fix
the following warnings that have prevented a successful validate on PPC
Mac OS X recently:

Fixing this leads to:

There are also warnings compiling C code:

All warnings being fixed by patches to the respective files.
