The question I think needs to be asked is not that, but "what about the mingw and cygwin builds?".
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 versions.
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).
