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

------- Comment #1 from schwab at linux-m68k dot org  2010-08-18 08:19 -------
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.
