SDL_blit_N.c (BlitNtoNKeyCopyAlpha): fix -Wshadow warnings by adding _ suffix to the temp Pixel local in the DUFFS_LOOP. SDL_blit.h (ASSEMBLE_RGB): add _ prefix to temp Pixel locals to avoid any possible shadowings. The warnings were like the following: In file included from src/video/SDL_blit_N.c:26:0: src/video/SDL_blit_N.c: In function 'BlitNtoNKeyCopyAlpha': src/video/SDL_blit_N.c:2421:24: warning: declaration of 'Pixel' shadows a previous local [-Wshadow] Uint32 Pixel = ((*src32 & rgbmask) == ckey) ? *dst32 : *src32; ^ src/video/SDL_blit.h:475:21: note: in definition of macro 'DUFFS_LOOP8' case 0: do { pixel_copy_increment; /* fallthrough */ \ ^ src/video/SDL_blit_N.c:2419:13: note: in expansion of macro 'DUFFS_LOOP' DUFFS_LOOP( ^ src/video/SDL_blit_N.c:2399:12: warning: shadowed declaration is here [-Wshadow] Uint32 Pixel; ^
