this is one of those classic things where we could actually improve C for performance. the standard is restricting here - data that requires to be identical in all cases for network, file etc. purposes should be marked with a special keyword - or for legacy purposes we mark the ones we want the compiler to order for us. its more complicated than just keeping the size down though - you might want things to start on 64 or 128 or 256-bit boundaries as well - e.g. if your class contains aligned vector members and is itself aligned.
