ISO C allows

    1. #include <systemheader.h>
    2. #include "localheader.h"
    3. #include MACRO

where MACRO has to -- after all expansions -- give one of
the former two cases.  The FT_* macros are defined in
freetype/config/ftheader.h and freetype/internal/internal.h.

Except that the internal headers no longer exist in FreeType
2.2+.  Neither are defined the corresponding FT_INTERNAL_*
macros.  When a FT_* macro is undefined none of the cases
1.-3. occurs, the preprocessor sees literal

    #include FT_INTERNAL_OBJECTS_H

and complains.  Thus you get errors on lines correspoding to
inclusion of internal headers (through FT_INTERNAL_*
macros).
