commit 5e51b642f747547c737a7abbc37e65b0f630d188
Author: Justus Winter <justus at g10code.com>
Date:   Mon Feb 13 10:58:23 2017 +0100

    build: Use macOS' compatibility macros to enable all features.
    
    * configure.ac: On macOS, use the compatibility macros to expose every
    feature of the libc.  This is the equivalent of _GNU_SOURCE on GNU
    libc.
    --
    Not defining this leads to compilation errors or superfluous warnings
    on macOS.
