Bug description:  php segfaults on some queries using pdo_odbc & ibm-db2 on a 
64bits platform

Description:
------------
On our both platforms (32 & 64 bits), we have php compiled with support
for IBM DB2 database via pdo_odbc extension. We ran into unexpected
segfaults deploying a new application on a 64 bits server.

We have tested several client version of DB2 but nothing helped.

At last, it seemed that pdo_odbc extensions did not compile properly, as
we got several warnings like :

passing argument 2 of 'SQLRowCount' from incompatible pointer type

Bug #32830 (related to odbc, not pdo_odbc) points out the same issue.

We wrote a little patch that works for us (tm), available at :

http://huan.ac-poitiers.fr/pdo_odbc_db2-x86_64.patch

Rgds.

Reproduce code:
---------------
<?php
  $toto = new PDO("odbc:mydb","user","password");
  $req = "SELECT ETA_DENOMINATION FROM ETABLISSEMENT WHERE ETA_DEPARTEMENT
= 16 AND ETA_RNE = '0160001P'";
  $machin = $toto->query($req);
  $truc = $machin->fetchObject();
?>


Expected result:
----------------
nothing indeed :-), it's just a script we used to isolate a query which
crashes only on our 64bits servers (of course, it works fine on 32bits
platform).

Actual result:
--------------
segfault... unless the value of ETA_DENOMINATION is not NULL.
