Problems with Data Types, Low Severity (2)

	Change	Effect
1	Name of member with value 1 has been changed from MEMCACHED_BEHAVIOR_BLOCK to MEMCACHED_BEHAVIOR_TCP_NODELAY.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

memcached.h
[+] enum memcached_behavior (1)
[+] enum memcached_return (1)

	Change	Effect
1	Value of member MEMCACHED_MAXIMUM_RETURN has been changed from 24 to 25.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
