No = standardization on this point, it seems. :-/ For this specific compile error, we could put in a little crutch like: #if defined(bit_SSE4_2) && !defined(bit_SSE42) #define bit_SSE42 bit_SSE4_2 #endif Thoughts? -Dimitry --Apple-Mail=_AED8B5FE-73A7-43E5-A8C8-26E8D4724608 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAld8AgIACgkQsF6jCi4glqOapgCcC3v9txvrsrusVLR3eX1zdtxM TbMAnjTixK0yKeWSB72IpshlJlGlM3Fu =I8s+ -----END PGP SIGNATURE----- --Apple-Mail=_AED8B5FE-73A7-43E5-A8C8-26E8D4724608--
