Description:
------------
The build failed with a duplicate symbol error:

ld64-74.4 failed: duplicate symbol _php_bz2_filter_factory in 
ext/bz2/bz2_filter.o and ext/bz2/bz2.o 

This was solved by adding extern to the php_bz2_filter_factory 
declaration in ext/bz2/php_bz2.h

An identical problem happened with Zend/zend_ini_scanner.c with the 
yytext declaration on line 478 (there is an earlier declaration in the 
same file which is already declared extern).





Reproduce code:
---------------
CFLAGS=-fast ./configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --disable-dependency-tracking --with-apxs2=/usr/sbin/apxs --with-ldap=/usr --enable-cli --with-zlib-dir=/usr --with-xml --enable-exif --enable-mbstring --enable-mbregex --enable-sockets --with-curl=/usr --with-config-file-path=/etc --sysconfdir=/private/etc --with-mysql-sock=/tmp/mysql --with-mysql=shared,/usr/local/mysql --with-mysqli=shared,`which mysql_config` --with-pdo-mysql=shared,`which mysql_config` --with-openssl --with-xmlrpc --with-xsl=/usr --with-pear=/Library/PHP --with-bz2 --enable-bcmath --disable-cgi --enable-zip --enable-memory-limit --enable-pcntl --with-zlib=/usr --with-zlib-dir=/usr --with-ldap --enable-memcache

5.2-latest fails in exactly the same fashion:

ld64-74.4 failed: duplicate symbol _php_bz2_filter_factory in 
ext/bz2/bz2_filter.o and ext/bz2/bz2.o

The fix is identical.

What compiler (and version) are you using?
Does this happen if you don't set the CFLAGS?
 [2007-10-03 00:49 UTC] chris at improbable dot org 
This is still a problem with 5.2.4. This affects the stock gcc (i686-
apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc. build 5367)) 
with or without CFLAGS=-fast
