Subject: PATCH: zsh-3.1.5-pws-6: some basic cygwin path handling fixes

There are some problems with zsh's pathname handling that don't work
when cygwin's (poorly thought out) drive letter hacks are in effect:
1) "//<drive-letter>/dir" is a valid path. builtin.c's fixdir()
strips off double slashes, which breaks things.
2) If you chdir("..") while in //D you're put in "/" but "/D" is not a
directory in "/". This breaks zgetdir(). (there is actually
another bug in cygwin that breaks zgetdir(), but that is a moot
point after my fix)
The fixes:
For #1, I just allow a leading // under cygwin.
For #2, I just have zgetdir() call getcwd() under cygwin. I
considered having zgetdir() use getcwd() for all systems that had it.
I know the Linux kernel now has a getcwd() syscall, which is
presumbably much faster than zgetdir(). But I backed down from this
for fear that all the magic going on in zgetdir() works around bugs in
some system's implementations of getcwd().
