so mingw  4.7.0 has same packing behavior of linux gcc, why in _mingw_ =

4.7.0 should I add -malign-double to be compatible with mingw  4.7.0 and msvc

abi?

I've also tested with -malign-double and nothing changes, I don't need mingw32

abi on linux, I need mingw abi on mingw, somehow changed with 4.7.0, I'm not

sure if it's a bug or not

That's how it is defined by the respective ABIs.  On i386-linux a struct field
has at most 32-bit alignment.  Add explicit padding or compile with
-malign-double if you want to be compatible to the mingw32 ABI, but that won't
be the only difference between those ABIs.
