Define a macro as:

ALIGN_STRUCTFIELD(type) ((int)(offsetof(struct {char a; type b;}, b)))

which gives the actual alignment of types in a structure.

The simpler: __alignof__(struct {type b;}) also works.

I'll have to try that out.

For now, as the previous version made it through all my tests, I may be pushing it, but change it to this for simplicity if that also works and passes all my test.

Thanks,
