I've uploaded a new set of the 1.0.8 Win32 binaries, development
libraries and Python bindings:
http://subversion.tigris.org/files/documents/15/17283/svn-win32-1.0.8.zip
http://subversion.tigris.org/files/documents/15/17293/svn-win32-1.0.8_dev.zip
http://subversion.tigris.org/files/documents/15/17281/svn-win32-1.0.8_pdb.7z
http://subversion.tigris.org/files/documents/15/17292/svn-win32-1.0.8_py.zip
The MD5 checksums are:
62c59a6d43e4d1d8f50cabbd50b7530b svn-win32-1.0.8.zip
5d1c0aa75c896cad48a45649f4028320 svn-win32-1.0.8_dev.zip
b01005d709788da422621cd68590d4e3 svn-win32-1.0.8_pdb.7z
ddb90fda3b1ca9af174c5b7510997c4f svn-win32-1.0.8_py.zip
These binaries use statically-linked apr, apr-iconv and apr-util.
