  Bug#21543: 5.0.24 breaks ABI compatibility for python bindings: \
  	InterfaceError on connect
  
  Removed the bool flag from the st_mysql_options struct, since it adds 
  another word in size to the memory size and shifts member memory locations
  down, both of which break binary-interface compatibility.
  
  Instead, use a flag, 2**30, in the client_options bit-field to represent
  that the client should check the SSL certificate of the server.

  include/mysql.h@stripped, 2006-08-25 11:54:31-04:00, cmiller@stripped +0 -1
    Do not change the struct size.

  include/mysql_com.h@stripped, 2006-08-25 11:54:31-04:00, cmiller@stripped +4 -2
    Add a new bit-flag for client verifying server SSL certificate.
    
    Emphasize that we're not stepping on anyone else's bit/toes.

  sql-common/client.c@stripped, 2006-08-25 11:54:31-04:00, cmiller@stripped +5 -3
    Set and read the bit-field for client-side SSL-cert checking of the server.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
