GCC 4.6 seems to be more picky about trying to stuff 64bit values into 32bit variables (as it should!). All the cases seem safe to fix by forcefully casting the value, since it seems either impossible (ByteCodeGenerator, UTF8, ...) or extremely unlikely (the string length in FontGtk) that the value would overflow a 32bit value. At worst, we are not really making things worse, but of course in some cases it might make sense to change the code to not force a cast here.
