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...
