They should be fixed. Almost all of them are due to the compiler doing whats
allowed there per it's docs and optimizing things. If you don't want items
potentially re-ordered you have to add the volatile attributes.

I'd rather be able to run (at my choice) with a compiler that will actually
optmiize for my current processor rather than the original x86 model only..
