proftp编译出错 哥哥们看看

我用的 proftpd-1.2.9 ＋proftpd-mod-quotatab-1.2.11.tar.gz＋mysql-4.0.25  
编译时用的./configure --prefix=/usr/local/proftpd --with-modules=mod_sql:mod_sql_mysql:mod_quotatab:mod_quotatab_sql --with-includes=/usr/local/mysql/include/mysql --with-libraries=/usr/local/mysql/lib/mysql没有提示错误
路径也没有错啊，
但是make时提示
mod_sql_mysql.c:1298: warning: statement with no effect
mod_sql_mysql.c: At top level:
/usr/include/gconv.h:176: warning: array '__data' assumed to have one element
/usr/include/bits/socket.h:237: warning: array '__cmsg_data' assumed to have one element
make[1]: *** [mod_sql_mysql.o] 错误 1
make[1]: Leaving directory `/home/linuxsoft/proftpd-1.2.9/modules'
make: *** [modules] 错误 2

哥哥们看看啊 问题在哪，
