Hello.
I'm trying to install nginx 1.0.11 on Centos 5.7 x86_64. Server runs cpanel, so this version and compliling from source are mandatory. Nginxcp.com provides cpanel plugin, and I'm using its installation script. But it's failing. I was able to track it down to this: ./configure: error: can not define uint64_t
I've found a solution here at mailing lists that suggests adding CFLAGS="", but it doesn't work. I've downloaded sources from nginx.org to be sure, and it still doesn't work:

root@server [/usr/local/src]# wget http://nginx.org/download/nginx-1.0.11.tar.gz

I've also tried applying the patch from http://nginx.org/pipermail/nginx-devel/2010-November/000548.html, and didn't help, too. Same goes for nginx 1.0.12.

My environment:
root@server [/usr/local/src/nginx-1.0.11]# cat /etc/redhat-release
CentOS release 5.7 (Final)
root@server [/usr/local/src/nginx-1.0.11]# uname -a
