  Is something possibly dependent on GNU extended functionality,
  that putting
    #define _GNU_SOURCE 1
  in a header file could enable?
 
  Also, if there are local files in the same directory as the Makefile,
  could  -I. in the right rule be needed to trigger compiles?

  ... a couple things that caused me hiccups before, maybe too obvious for others.
