Description:
------------
when I build PHP 5.3.10 source with memcache extension, throw an error

/usr/local/src/php-5.3.10/ext/memcache/memcache_session.c:39: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘ps_mod_memcache’

and in the same environment, I build PHP 5.3.8 with the memcache-2.2.6, it's all OK

so I read the source, I found in 5.3.10, there is no define HAVE_MEMCACHE_SESSION, which I found in php-5.3.8/main/php_config.h, but not in any file of php-5.3.10

I guess php-5.3.10's configure file may have a mistake:
when use the parameter: --enable-memcache
not write 
#define HAVE_MEMCACHE 1
#define HAVE_MEMCACHE_SESSION 1
to the php_config.h

Test script:
---------------
tar zxf php-5.3.10.tar.gz

tar zxf memcache-2.2.6.tgz
mv memcache-2.2.6 php-5.3.10/ext/memcache
tar zxf APC-3.1.9.tgz
mv APC-3.1.9 php-5.3.10/ext/apc

cd php-5.3.10
rm -f configure
