This error is caused by the following line:

#include "ext/mysql/php_mysql.h"n#include "ext/pcre/php_pcre.h"n#include "ext/posix/php_posix.h"n#include "ext/session/mod_mm.h"n#include "ext/session/php_session.h"n#$
p_zlib.h"n

This line should be broken into multiple lines:

#include "ext/mysql/php_mysql.h"
#include "ext/pcre/php_pcre.h"  
#include "ext/posix/php_posix.h"
#include "ext/session/mod_mm.h"
#include "ext/session/php_session.h"  
#include "ext/standard/php_standard.h"
#include "ext/xml/php_xml.h"
#include "ext/zlib/php_zlib.h" 

The file can be manually edited after configuration and the build will proceed normally with success. However running configuration again will revert this file to the broken state again.
