Description:
------------
When trying to configure PHP 5 for compilation under SuSE Linux 8.1 (old system because it's a production server) and enabling MySQLi support I get this:

checking for MySQLi support... yes
checking whether to enable embedded MySQLi support... no
checking for mysql_set_server_option in -lmysqlclient... no
configure: error: wrong mysql library version or lib not found. Check config.log for more information.

The message seems clear but the problem is that in the given directory the MySQL 4.1.3 libraries exist (and only there - I used the RPM-devel from the official homepage). config.log ends with:

configure:54782: checking for MySQLi support
configure:54828: checking whether to enable embedded MySQLi support
configure:54961: checking for mysql_set_server_option in -lmysqlclient

/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char mysql_set_server_option();

int main() {
mysql_set_server_option()
; return 0; }

I already tried to apply the patch given in #29329 but that didn't work either. I also tried changing the paths and so on but that only resulted in the same error. The libraries are the right ones as the "normal" mysql support compiles just fine and phpinfo() gives me "MySQL client library: 4.1.3-beta". So normal MySQL support is working just fine with the libraries but MySQLi support is not. Why, what am I doing wrong?

Reproduce code:
---------------
PHP 5.0.0 source from php.net

./configure --with-openssl --with-zlib --enable-bcmath --with-bz2 --enable-calender --enable-exif --enable-ftp --with-gd --with-png-dir=/usr --with-jpeg-dir=/usr --with-zlib-dir=/usr --with-ttf=/usr --with-freetype-dir --enable-gd-native-ttf --with-gettext --with-iconv --with-imap --with-ldap=/usr --enable-mbstring --with-mime-magic --enable-sockets --enable-sqlite-utf8 --with-iconv-dir --with-xsl --with-apxs2=/usr/local/apache2/bin/apxs --disable-libxml --with-mysql=/usr/lib/mysql --with-mysql-sock=/var/lib/mysql/mysql.sock --with-mysqli=/usr/bin/mysql_config

(libxml2 is disabled because I can't upgrade to a newer version right now because of the old glibc in 8.1 - but that shouldn't matter ... or?)

Expected result:
----------------
./configure should finish successfully - as well as the make afterwards, of course ;-)

Actual result:
--------------
./configure aborts due to the missing MySQL libraries which are defenitively there.
