For MinGW/32, 1) what happens if you use -m[no-]ms-bitfields?  (See
https://gcc.gnu.org/onlinedocs/gcc/Variable-Attributes.html,
section 6.38.5 i386 Variable Attributes).  Or 2) what about using
__attribute__((packed))?  Stefan doesn't like it for an obvious reasons,
but may be just for this particular case...
