Theoretically, yes, however no compiler I know of actually does
this, since many data structures are used for raw "wire" or "file"
data (i.e. TCP/IP headers, etc.) and any compiler that actually
implemented this would instantly break existing code.

[Personally, I think the re-order addition to the C spec was
 not thought out well, and does not even spell out a portable
 way for legacy code to retain backwards compatibility, e.g.
 with a #pragma or whatever...]
