The idea of > merging the i386 and amd64 headers into a common area seems like a > better idea to me. For now my goal was to merge headers that can be used by user code so it can be compiled with -m32. Eventually, I think it would be nice to merge all headers and install x86/ as machine/ for both i386 and amd64. That would make the x86 headers similar to powerpc and mips headers (and arm when 64bit support is added there). I think I still have one or two (untested) patches. I'll have a look at it during the weekend. --------------enigE8133964C8851F885FB99C4D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iF4EAREIAAYFAlA1PH4ACgkQfoCS2CCgtiv52AD+Loo7vrNn6Bdfbxyc+Hsg7VPf f1tl5sdN/0jcLP1WhVEA/AxM1R+D8yP1DN9XphBV4IZzo9E2k6BbjNwGmsEz/vnL =ge49 -----END PGP SIGNATURE----- --------------enigE8133964C8851F885FB99C4D--
