>Description:
	I was trying to use apache2 with APACHE_MPM=worker and www/websvn,
	a cvsweb alike for subversion, which requires ap-php+php-zlib.

	It works perfectly when using defaults (APACHE_MPM=prefork), but
	not with APACHE_MPM=worker (which uses threads), the httpd log
	was saying:

PHP Warning:  Unknown(): Unable to load dynamic library 
'/usr/pkg/lib/php/20020429/zlib.so' - /usr/pkg/lib/php/20020429/zlib.so: Undefined 
symbol "output_globals" (symnum = 61) in Unknown on line 0

	I've been looking at the code of php-zlib, and I think the missing 
	symbol is inside an #ifdef ZTS block, I think it's used for multithreads
	support.

>How-To-Repeat:
	cd www/apache2 && make APACHE_MPM=worker && cd ../websvn && make install
	[ configure php.ini to load zlib.so]
	See /var/log/httpd/error_log for the error.

>Fix:
	Sorry, I don't know... and I wish to know!
