than FreeType:

Garret Rieger b14475d2ae [subset] further changes to serializer error handling. 
- Rename enum type and enum members.
- in_errors() now returns true for any error having been set. hb-subset now looks for offset overflow only errors to divert to repacker.
- Added INT_OVERFLOW and ARRAY_OVERFLOW enum values.

Garret Rieger 73ed59f7a6 [subset] store errors in the serializer as a flag set. 
Make check_assign/check_equal specify the type of error to set.

Behdad Esfahbod fa333e34d6 [vector] Remove static_array 
Was good idea, but with C++ types with constructor/destructor, was getting in
the way as compiler was destructing those items where it was not desired.
Since C++ does not allow zero-sized arrays, just remove it...
