Message : [raccess] Modify for PIC build. Based on the patch provided by Erik Dahlstrom <ed@opera.com>, http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()' are renamed with `ft_' suffixes. * src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed to `ft_raccess_rule_by_darwin_vfs()'. * src/base/ftobjs.c: Ditto. * src/base/ftrfork.c: Declarations of FT_RFork_Rule, raccess_guess_rec, are moved to... * include/freetype/internal/ftrfork.h: Here. * include/freetype/internal/ftrfork.h: FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined to replace raccess_guess_table[] in both of PIC and non-PIC modes. * src/base/ftrfork.c: raccess_guess_table[] array is rewritten by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}. * src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table' storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve the function pointer from `ft_raccess_guess_table' storage in `BasePIC' structure. * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with FT_RACCESS_GUESS_TABLE_GET. (raccess_get_rule_type_from_rule_index): Add `library' as the first argument to the function, to retrieve the storage of `ft_raccess_guess_table' from it. Also `raccess_guess_table' is replaced by FT_RACCESS_GUESS_TABLE_GET. (ft_raccess_rule_by_darwin_vfs): Ditto.
