Description:
------------
On Fedora core 17 (64 bits), with php 5.4.5 (latest version), when I build 
yaz.so, there is an undefined symbol pval_destructor

I followed the standard procedure to download php-yaz and to build it (see test 
script below).

version info;

yaz 4.2.17-2 (obtained via yum install yaz)

php-yaz version 1.1.3
php 5.4.5-1

When I run make test, it complains about an undefined symbol "pval_destructor"

I had this problem earlier with php 5.4.4, then I installed php 5.4.5 from the 
fedora updates-testing repository and the problem disappeared, but now it is 
happening again



Test script:
---------------
cd /root
mkdir tempo
cd tempo
pecl download yaz
gunzip yaz-1.1.3.tgz 
tar xvf yaz-1.1.3.tar 
cd yaz-1.1.3/
phpize
./configure 
make

make test

Build complete.
Don't forget to run 'make test'.
