yeah, changing that typedef + true def to plain include <stdbool.h>
makes it progress to the next failure, which is in cross compilation
environments, such as using fedora 24 + the Android NDK to try to build
a ARM android binary.

On the bright side, in addition to alpine:3.4 now these are building ok:

3 archlinux:latest: Ok
4 centos:5: Ok
5 centos:6: Ok
6 centos:7: Ok
7 debian:7: Ok
8 debian:8: Ok
9 fedora:20: Ok

Waiting for some extra cross compilation envs to check that hunch...
