Here's something weird.  I don't know whether this is a problem with the
latest Cygwin, or bash:

$ /bin/mount -f -u c:/ /a/b
$ /bin/sh -c 'cd /a/b && /bin/ls | head -1'
sh: line 0: cd: /a/b: No such file or directory
$ /bin/bash -c 'cd /a/b && /bin/ls | head -1'
AUTOEXEC.BAT
$

Some system info:

$ /bin/uname -svr
CYGWIN_NT-5.1 1.5.18(0.132/4/2) 2005-07-02 20:30
$ /bin/bash --version
GNU bash, version 3.00.16(11)-release (i686-pc-cygwin)
Copyright (C) 2004 Free Software Foundation, Inc.
$ /bin/sh --version
GNU bash, version 3.00.16(11)-release (i686-pc-cygwin)
Copyright (C) 2004 Free Software Foundation, Inc.
$ /bin/cmp /bin/bash.exe /bin/sh.exe && echo same
same

Huh?  Strace shows that sh fails when trying to stat /a.  Does this,
perhaps, have something to do with bash switching to POSIX mode when
invoked as "sh"?

If there's any real truth it's that the entire multidimensional infinity
