mmh. Looks like the "lack of wide charakter support in cygwin" issue.
There are several threads about that one on the devel mailing list.

Why don't you use "--force-update" option for
From --help:

 --force-update do an SVN update (if applicable) instead of a clean
                                checkout, even when performing a full run

That would prevent a new checkout and simply update the existing working
copy. Using a fresh checkout each time is simply wasting bandwith...

Well, there have been some changes to Boost.Config recently.
From boost/filesystem/config.hpp I get the impression that
BOOST_NO_STD_WSTRING is/was not defined for cygwin...

And using "update" instead of a full checkout should bring some
speedup. Maybe upgrading to svn 1.6.1 might speed things up, too.
