Hi Behdad (or Martin),

It looks like things are currently (80af2812fb3b231ddcb4608ec13c6038a681c818) a little broken with regard to #includes....

First, hb-shape.cc fails to compile because hb_ot_shape() has not been declared; it needs to #include "hb-ot-shape.h".

And second, hb-ot.h is a public C-language header and as such, it should not include hb-ot-shape-private.hh, which is a private C++-language file. Changing hb-ot.h to include hb-ot-shape.h instead seems to resolve this.
