- Lots of indenting changes - VC++ is strict with variadic macros - VC++ does not accept unistd.h - new interface for walltime - VC++ does not seem to have support for integer overflow. - VC++ defines YENV_REG? - no access flags, x permissions ignored. - new FindGMP supporting MPIR - make horus optional (c++ is hard).
