Description:
------------
After Net-SNMP team supplied patch to net-snmp 5.2 to correct a coredump under certain situations, php 4.3.8 would no longer compile.  4.3.9 had exact problem as 4.3.8.  4.3.10 had an error similar to bug #31121 (way too much error detail to attach but I have it if you want it).  Following #31121 I downloaded CVS snapshot for 200503181930 and 200503191330 and both had a ld error while ld sapi/cli/php.  DSO appeared to ld correctly.  Details of all in Actual Results Section of this bug report (including net-snmp patch - dif.proto).  

ENV is HP-UX 11.11i, GMAKE 3.80, GCC 3.3.3, Apache 2.0.53, MySQL 3.23.58, Net-SNMP 5.2(patched).  Any other questions, please email.  Thanks.

Expected result:
----------------
Successful compile.

Actual result:
--------------
Failure on 4.3.8 and 4.3.9 compile after applying net-snmp 5.2 patch

Sorry, forgot to add config options.  Using same options on all versions to compile.

We don't support any patched external libs, we can hardly support really released ones..

[2005-03-19 22:43 UTC] phdokc at cox dot net

Sorry, should have been clearer.  I backed out the net-snmp 5.2.1 patch and the CVS snap shot and 4.3.10 still will not compile and have the same error results.

[2005-03-20 01:12 UTC] sniper@php.net

Sorry but this is not PHP bug. Compiles fine for me with latest CVS snapshot.
