OS X 10.5.{6,7} GCC 4.2.1 Non-debug Build Fails

[rue]

Apparently the -O2 flag causes some type of a problem; -O1 etc. work fine, as does rake build:debug (-O0). Using GCC=gcc-4.0 on the same system works without problems.

This appears to be specifically related to the compiler. This is the end of the build output, same error occurs e.g. trying to run bin/mspec.

Rework the rotate instruction (gcc 4.2 fix)

The old code somehow exposed a bug in gcc 4.2. This code seems to work
fine on 4.2 and 4.0.
