Sorry, I don't understand... Binaries would remain linked to
svn_error_clear, whilst the svn_error_clear() macro would automatically
redirect newly compiled code to the new svn_error_clear2() function.
AFAICS, you retain binary and source compatibility. But then I always
have had trouble understanding compatability rules!
