svn client and long filenames on Windows

Hi all,

I have a set of developers who have a habit of checking in extremely long
filenames in subversion repositories on a Windows platform. They do this
using TortoiseSVN, which works, but when an attempt is made to check out
the code as part of a maven build, the error below is thrown.

At the core of the problem is the Windows limit of 256 character paths. I
suspect TortoiseSVN works around the problem by changing to each directory
before accessing a file, however the subversion client seems to want to
access files in one go relative from the current directory, which then
breaks with "path too long".

Is this something easy to fix in the subversion client?

The error is:

[INFO]
------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO]
------------------------------------------------------------------------
[INFO] Unable to checkout from SCM
Provider message:
The svn command failed.
Command output:

Docs\.svn\tmp\text-base\INSTALLATION INSTRUCTION FOR SCMBExcelTools for
Excel 2000 (Hong Kong Version).doc.svn-base': The system cannot find the
path specified.

Regards,
Graham
