ce33a312da FT_USE_MODULE declares things as: 
extern const FT_Module_Class

(or similar for C++).  However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.

To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:

  All declarations that refer to the same object or function shall
  have compatible type; otherwise, the behavior is undefined.

(And they are not compatible types.)

Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does.  (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

Patch from Savannah bug #25133.

* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

* builds/amiga/include/freetype/config/ftmodule.h,
include/freetype/config/ftmodule.h, */module.mk: Updated to declare
pass correct types to FT_USE_MODULE.

e6e6eade04 Finish fix of scaling bug of CID-keyed CFF subfonts. 
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.

* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).

* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results.  This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.

* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.
Update all callers.
(cff_slot_load): Handling scaling of subfonts properly.

* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
(cff_parse_font_matrix): Use it.

* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.

* docs/CHANGES: Document it.

the CJK-specific functions.

* include/freetype/config/ftoption.h (AF_CONFIG_OPTION_INDIC): New
macro.
* devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.

46dde4953a * src/autofit/aflatin.c (af_latin_uniranges): Expand structure to 
cover all ranges which could possibly be handled by the aflatin
module (since the default fallback for unknown ranges is now the
afcjk module).  It might be necessary to fine-tune this further by
splitting off modules for Greek, Cyrillic, or other blocks.
