Description:
------------
When I try to compile php-5.2.1 with net-snmp-5.3.1, I get configure: error: SNMP sanity check failed.
php-5.1.6 with net-snmp-5.3.1 also has the same problme.
But, php-5.1.6 with net-snmp-5.0.7 has no problem.
php-5.2.1 with net-snmp-5.0.7 also has no problem.

Reproduce code:
---------------
On RedHat9.0
#tar zxvf net-snmp-5.3.1.tar.gz
#cd ./net-snmp-5.3.1
#./configure 
#make;make install
#cd ..
#tar zxvf php-5.2.1.tar.gz
#cd ./php-5.2.1
#./configure --with-snmp=/usr/local 

Expected result:
----------------
Will get fine mesage:
Thank for using php.
Then you can #make
,php-5.2.1 with net-snmp-5.0.7 is fine.

Actual result:
--------------
you will got failed.
