I'm not sure, but the comment seems to indicate that we don't want to use it: ;; According to ;; http://sourceforge.net/projects/libjpeg-turbo/ , ;; "libjpeg-turbo is a derivative of libjpeg that ;; uses MMX, SSE, SSE2, and NEON SIMD instructions ;; to accelerate baseline JPEG compression/ ;; decompression", so we had better not use it But I'm not sure how to interpret that, so I've copied Andreas on my reply (he wrote that comment). --ftEhullJWpWg/VHq Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEsFFZSPHn08G5gDigJkb6MLrKfwgFAlg7Uv8ACgkQJkb6MLrK fwiDlBAArfiMcnhj8jC5OQ4Bqyo3xaH8MxKp2sGDRJP1cFqbndD4Tsbm5oXl7LXW cC0J9DYjpohdlppTVCLnCI8Gbr8bkcmYMsX/u2WEpJwArNin16+lvmHBaM7CTRZD 9Of5vlanFLPyceHwYPX0OuDDxhxbLt6FtB6HnkoZ9jnPIZY6oOFjzRZrPtAu5hOR jsmJ5t56TrIRaE+C0/yNXlw/xwWxIf2klEb0MywvJaJIPbJ9BW49hdXBsXV0fAHQ C3ZBHVGKK2fYhxa2hFvOvarLEnySredRk26085WdFTGzthzP8z8l9H54OD1nUnHd gxJEklW5MTetavlsygiDP4xoqK8UdNenj7QLYMh4VAGB75y7IRNhpTSZCqJdW0SE FU/vxy7viJaZF5+t71Shg0IcYyIyPVGcibgvlW+T5wnBEVtIMg7hNhfFTuREq06C bpbSgwZS1RGQ9JQnU0xDRay2bb2y7oviPOPTp0qanyj8VnmMXd79B1LEWWgxDrut NSI8/HNBqND64mpcbbe48dXVsoTCoE1fu3uz/4uURUBZPsjNSBjA9nWFhrYoAn/1 5T52kSwPYUk62ahABeM6alAdOz9+X0Q+Ra3HyedQ/YxetiHKm6VdOs/yaoj19xrM l3MmR0xFed8KNJgBNFIluQfYWvoIvpEJJuR4/xEfmoZplV4HOM8= =B79o -----END PGP SIGNATURE----- --ftEhullJWpWg/VHq--
