PATCH: compdump with HOME=/

[Peter Stephenson <pws@cambridgesiliconradio.com>]

Further to the messages about zsh under cygwin earlier in the week...

I've just installed cygwin and compiled zsh.  Without the fix I posted,
undefining HAVE_MMAP as suggested by Geoff, external programmes don't work;
with it, everything went flawlessly: the only minor fly in the ointment was
that my home diretory came up as / and compdump rewrote this as //, which
apparently cygwin can't cope with (or it couldn't this time).  Everything
else I tried worked, including the new completion system, running other
cygwin executables, running WIN32 executables, basic job control.  This
seems a pretty good test of the basics.  (Actually, I was astonished.)

$OS is set to Windows_NT, $MACHTYPE is i686; it's a Pentium III running
Windows NT 4 sp 5 with the latest available cygwin release.
