PATCH: compilation on cygwin

[Peter Stephenson <pws@cambridgesiliconradio.com>]

This is the note I'm adding for compilation on cygwin.  It requires a
few recent changes: not using mmap() for memory management (this is in the
zsh-3.1.7-pre-4 pre-release), a missing header needed by zftp, and a
missing function in mathfunc (these aren't).  If anybody thinks the
information is otherwise incorrect, please let me know.

+	There are currently problems installing files, due to the
+	installation scripts not realising the executable has a .exe

+	and run `make install.fns; make install.man' in the top-level
