Looking into the `TLAYOUT' branch of FreeType 2's CVS (which contains
Masatake's extensions to make the OpenType stuff work with
FreeType 2), I see that the function is defined like this:

  FT_Error  TT_Load_GSUB_Table( FT_Face          face,
                                TTO_GSUBHeader** retptr,
                                TTO_GDEFHeader*  gdef )
So you directly have the `FT_Face' structure available!

The same is true for FreeType 1:

  TT_Load_GSUB_Table( TT_Face          face,   
                      TTO_GSUBHeader*  retptr,
                      TTO_GDEFHeader*  gdef )

Here you have to use the `TT_Get_Face_Properties' function to extract
the value of the `num_Glyphs' variable.
