on both Unix (SVR4 and BSD) and Windows. Restores behaviour of passing -1 for anonymous memory on Unix. Use MAP_ANONYMOUS instead of _ANON since the latter is deprecated according to Linux (gentoo) man pages. Should we continue to allow mmap.mmap(0, length) to work on Windows? 0 is a valid fd. Will backport bugfix portions.
