Import of upstream 1.0.18 breaks build

[mvanbaak]

After the merge of the upstream 1.0.18 import, this does not compile anymore.
The version before that compiled fine.

I followed the instructions as given in the README on a clean Amazon Linux EC2 instance.
(started AMI id ami-9398d3e0, ran "yum update -y", installed the packages as stated here in the README, ran the configure and make commands)

We really need this as we have to compile the module by hand (we dont want the igbinary module installed on our instances, as doctrine/cache breaks if we have RedisCache with igbinary)

I'm seeing the exact same build errors on CentOS 7.

BTW -- my reasons for building are a little different -- we want to use the module with PHP 7.1, so it has to be built against PHP API=20160303. The binary provided in the AWS console is linked against API=20151012.

For now I put my ansible plays to use 1.0.8 as it seems to work ok with php 7.0 ;-)
