I've been looking at some of the remaining regressions, and I have a fix for the issue here: http://tinyurl.com/yq6a5o I'm a little bit dubious about this patch, because I don't believe the fix should be necessary in the first place (can't understand why the compiler's complaining in the first place!), however it does fix the issue and appears harmless for the msvc/intel/gcc/borland compilers I've tested with. OK to go ahead and apply?
