Ah, it's because of the Bash POSIX mode:
6.11 Bash POSIX Mode
====================
[ ... ]
When invoked as `sh', Bash enters POSIX mode after reading the
startup files.
[ ... ]
19. If `CDPATH' is set, the `cd' builtin will not implicitly append
the current directory to it. This means that `cd' will fail if no
valid directory name can be constructed from any of the entries in
`$CDPATH', even if the a directory with the same name as the name
given as an argument to `cd' exists in the current directory.
That's why it didn't work even though sh == bash under cygwin and it works
fine in bash.
cheers,
