Fixed bug 3746 - remove SDLCALL attribute from SDL_BlitFunc() funcptr Ozkan Sezer The attached patch removes SDLCALL attribute from SDL_BlitFunc() funcptr. As far as I can see, *SDL_BlitFunc() is completely internal to SDL with no specific calling convention requirements. The actual functions assigned to SDL_BlitFunc seem to not have any calling conventions specified. So, easy solution is simply removing the strict calling convention from the type.
