A number of public functions in mod_dav.h aren't properly exported with DAV_DECLARE. This recently became a problem for Subversion, because mod_dav_svn now supports DAV locking, and mod_dav's locking functions were amongst the ones that were not exported. Nobody noticed this on Unix where DAV_DECLARE is a no-op, but Windows suffered mightily.
The attached patch (against the 2.0.x branch) fixes the problem. I had to use DAV_DECLARE_NONSTD in a few places where the functions are used as callbacks, because I didn't want to fiddle with the __stdcall horror in callback parameter declarations.
Subversion 1.2, which will introduce locking functionality, will not work as a DAV server on Windows without an httpd-2.0.x release that includes this patch. I hope such a thing is possible in the next few months, and I'm only sorry I was too late for the the 2.0.53 release.
I've committed it to trunk and have proposed it for backport. -- justin
P.S. I had 'fun' trying to get your name in the commit log. I hope I got it right... =)
