bugs in chdir()?

[Kazuhiro Fujieda <fujieda at jaist dot ac dot jp>]

Please look into the following sessions changing the current
directory to C:\TEMP.

Case 1. (No problem)
$ cd /cygdrive/c/TEMP/	# Use POSIX style path with a trailing slash.
$ pwd 
/cygdrive/c/TEMP        # Good.

Case 2.
$ cd C:/TEMP/		# Use Win32 style path with a trailing slash.
$ pwd
/cygdrive/c/TEMP/	# The trailing slash is left illegally.

Case 3.
$ cd '\TEMP'		# Use Win32 style path with a backslash.
$ pwd
/TEMP			# No such directory.

I think they are not bugs of chdir(), but bugs of the path
conversions and revealed via chdir(). The strace logs are
attached below.
