Or just backport the fix to 7.x :)  The server is only sending 32 bytes
regardless, so having the fix in older client library versions will
give either the right sbc number (if the server is new) or 0 if the
server is old (unless you've wrapped the sbc_lo field and sbc_hi is
set).  So an improvement either way.
