I'm surprised by this.  Doesn't mkoctfile include -lhdf5 if it is 
needed? Which things break and how?

The current CVS uses $(CC), which should expand to gcc.  Can you please 
check what it is for your version?

Not true on my 10.3 box, but maybe I have a different version of libpng 
(1.215) or Octave (2.1.69).

        #include <png.h>
        #include <octave/oct.h>
