- Add <cstring> to JASGadget.h, <cstdarg> to JUTDbPrint.cpp
- Fix <string> -> <cstring> in JUTFont.h, d_save.h, f_ap_game.h
- Fix std::isnan usage in c_cc_d.cpp
- Fix cCcD_Src types: s32 -> u32 for bitmask fields (upstream fix)
- Fix AT_TYPE_WOLF_ATTACK/AT_TYPE_UNK unsigned literals (upstream fix)
- Remove (s32) casts on hex literals in collision data (upstream fix)
- Fix 0xFFFFFFFF literal in d_a_obj_wood_statue.cpp (upstream fix)
- Add braces to case 0 in d_a_e_gb.cpp to fix jump-over-init
- Fix Z2AudioCS.h include path (Z2AudioLib -> Z2AudioCS)
- Forward-declare Z2AudioCS in stubs.cpp to avoid revolution conflicts
- Guard JASGlobalInstance specializations with __MWERKS__ in m_Do_main
- Remove duplicate inline functions from d_com_inf_game.h
