The core of zlib shouldn't have any POSIX dependence; it just takes buffers of bytes and produces buffers of bytes. It has some convenience functions for decoding files given a path or FD, but I'm sure Fuscia's limited POSIX compatibility layer will support that, basic file access is relatively easy to provide in a POSIX library wrapping Fuscia's file handling. Likewise, I'd be willing to bet that curl and Git would mostly work on top of the limited POSIX compatibility layer; they might need a few tweaks, but likely not much more than the tweaks needed in porting to the various BSDs and OS X, and likely a lot less than is needed to provide them natively on Windows.
