Cygwin has their own implementation of fork(). So the fix there has to be
done in cygwin and not us - presumably they have either already fixed it,
or will fix it in order to get general compatibility with the new ASLR

Mingw is a different story. But some googling indicates that mingw disables
ASLR by default. You need to specify --dynamicbase if you want to to be
dynamic, which we don't. (Being mingw I've not managed to find any actual
docs, but for example
http://lists.cypherpunks.ca/pipermail/otr-dev/2012-August/001373.html seems
to indicate it has to be enabled).
