I'm not sure why it would matter, presumably Cygwin isn't compiled with any flags that would enable SSE/SSE2 instructions and so there wouldn't be any need to have a 16-byte aligned stack in between the time mainCRTStartup() is called by Windows and main() is called by Cygwin. But, I notice that on my machine that Windows just happens to call mainCRTStartup() with a 16-byte aligned stack.
