mingw 32-bit: realign the stack in our callbacks
A default 32-bit mingw build assumes the stack is 16 byte aligned,
which appears to be a problem with gcc.
With quadmath enabled, libgcc includes instructions that require
16-byte alignment and access relative to the stack pointer, and
when the stack isn't aligned, results in a crash.
To prevent that add the force_align_arg_pointer attribute to our
callbacks for 32-bit gcc on Windows.
