Inconsistency in handling a DOS path between subversion commands

["ìíì (Trustin Lee)" <trustin at gmail dot com>]

I'm using Cygwin's subversion package instead of the native win32 build
provided by CollabNet.  It seems to work very well with UNIX-like paths,
but some commands doesn't seem to play well along with DOS paths.
Please take a look into the following log - 'svn info' works fine with a
DOS path but 'svn update' does not:

trustin@vault ~/workspace/netty-4.0
$ uname -a
CYGWIN_NT-6.1-WOW64 vault 1.7.7(0.230/5/3) 2010-08-31 09:58 i686 Cygwin

trustin@vault ~/workspace/netty-4.0
$ cygcheck -c subversion
