    In Win64 stdcall is the same as thiscall, cdecl, register, fastcall, anythingelsecall. 

    Do you know that all Win32 API declared with stdcall ? Are you going to say that Delphi 
Win64 applications wiil not be able to work with Win32 API  at all ? :-D

    There is no problem with calling conventions on x64 systems between modules by different
compilers as log as all compilers vendors follow the same rules about fastcall. And it seems 
they follow.
