OK, the problem is that svn is not working on the machine:

$ /cygdrive/c/Program\ Files\ \(x86\)/Subversion/svn info
svn: Can't determine the user's config path


However, this should not be an error.  That is the point of this test. 
Even if something is wrong, it should not error out.  It should continue 
unless it is required.  Perhaps the check_version_string function should 
be made aware that it should only error out if REQUIRED is set.
