Fixed bug 1225 - Altivec blitters broken due to SDL_PixelFormat

Browse source 
bastien.bouclet@gmail.com 2011-06-13 05:50:58 PDT

Static pixel format initialization has not been updated to reflect header
changes in SDL_blit_N.c

The attached patch fixes Altivec support for me. altivec.h is needed for some
systems.
