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.
