To my knowledge the only thing __cdecl and __stdcall do is affect the argument passing on the stack since 32 bit uses the stack to pass arguments. Since 64 bit passes arguments inside registers and then only later uses the stack if there are too many parameters to fit in the parameter registers (Basically permanent __fastcall), these specifiers are probably ignored in all 64 bit platforms
