SVN does not allow checking out parent dir if its child dir has been checked out

I'm using Subversion 1.3.0 (r17949) on Windows 2000 SP4.

Assume that I have a repository at h:/temp/SvnReps/ChjTrivials , and the
C:/ChjTrivials directory does not exist yet.

Now, I issue the command:
 
<pre>
C:\>svn co file:///h:/temp/SvnReps/ChjTrivials/trunk/ichsize
ChjTrivials/ichsize
</pre>

SVN outputs:

<pre>
A ChjTrivials\ichsize\ichsize.cpp
A ChjTrivials\ichsize\ichsize.dsp
Checked out revision 4.
</pre>

The checkout is success, and I have what I want in C:/ChjTrivials/ichisze

But, when I further issue the following command:

<pre>
C:\>svn co file:///h:/temp/SvnReps/ChjTrivials/trunk ChjTrivials
</pre>

SVN outputs:
 
<pre>
A ChjTrivials\ComHwCtrl
A ChjTrivials\ComHwCtrl\ComHwCtrl.cpp
A ChjTrivials\ComHwCtrl\ComHwCtrl.dsp
svn: Failed to add directory 'ChjTrivials\ichsize': object of the same name

already exists
</pre>

Why!!! For the second command, I just want to checkout the parent directory

of what the first command had checked out, and it could not cause any local

copy conflict if the second checkout is allowed. Why SVN prohibit that?

Why this make me mad? I'm developing a GNUmake-featured make system that
can automatically checkout the required source files(.cpp, .h etc) as
instructed in my makefiles, and those makefiles are often written to
checkout only part of a CVS or SVN repository(that part is enough for the
current makefile to build a project). Back to the time I used CVS, checking

out a child dir then its parent dir is not a problem, but when I upgrade my

make system to support checkout from SVN these days, I found this anonying
SVN behavior.

Do you kind guys have the same experience as I and any solution to this?

BTW: SVN 1.3.2 (r19776) exhibits the same behavior.

I first posted this problem on
http://www.svnforum.org/2017/viewtopic.php?t=1480 when I was unable to
subscribe to the svn official mailing lists. Please also vist that web page

for more discussions already existed.

Later, I posted this question to user@subversion.tigris.org for two weeks,
and have got only one response just confirming this SVN behavior, and I
hope you kind Subversion developers take my opinion into account and make
Subverion behave more reasonable.
