For Windows x86-32 targets, the Microsoft ABI only guarantees that the

alignment of the stack. However, before this commit, it did not realign the
stack unless SSE was also enabled.
When a stricter (larger) alignment is requested, it's always necessary to
realign the stack, as what Solaris does.
Yes, or else if you configure the compiler --with-fpmath=sse (which is IMO the
right thing to do for native 32-bit x86 platforms nowadays).

* config/i386/cygming.h (STACK_REALIGN_DEFAULT): Copy from sol2.h.
FWIW looks good to me.
Thanks, pushed to master branch.
