Win32 APR does

    FileTimeToAprTime(&finfo->atime, &wininfo->ftLastAccessTime);
    FileTimeToAprTime(&finfo->ctime, &wininfo->ftCreationTime);
    FileTimeToAprTime(&finfo->mtime, &wininfo->ftLastWriteTime);

and Subversion's svn_io_file_affected_time() does not expect mtime to
be less than ctime.

It's possible that APR should be changed to put the more recent of
create/last write into ctime. However that's really a separate issue
and need not concern us, I don't think Subversion should be using
ctime at all, it's only interested in the file contents. I'm going to
check-in a patch to make svn_io_file_affected_time always use mtime,
that is unless someone objects :)
