Description:
------------
libmemcached 1.0.4
memcached server 1.4.5
mysqlnd 1.2.0-alpha (10200)
php memcached 2.1.0

Even when the build process accepts and outputs that memcache support is enabled 
and built into 'shared' module, the handlers that are available remain the 
default and user ones. See below:-

#Available
array(2) { ["default"]=> array(2) { ["version"]=> string(5) "1.0.1" 
["version_number"]=> int(100001) } ["user"]=> array(2) { ["version"]=> string(5) 
"1.1.0" ["version_number"]=> int(100100) } }
#Setting
Catchable fatal error: mysqlnd_qc_set_storage_handler(): Unknown handler 
'memcache' 

#phpinfo shows for mysqlnd_qc
Handler	
default	default
nop	enabled
user	enabled
object	enabled


Test script:
---------------
No test script, build process was as follows

wget http://pecl.php.net/get/mysqlnd_qc-1.2.0.tgz

tar xzf mysqlnd_qc-1.2.0.tgz
# check/set correct permissions etc
cd mysqlnd_qc-1.2.0
phpize
./configure --enable-mysqlnd-qc-memcache
make
make install
