Of course, there sre still the ARM, MIPS and PPC architectures to support. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --45Z9DzgjV8m4Oswq Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.8 (FreeBSD) iEYEARECAAYFAkgDIzEACgkQ/opHv/APuIc5igCglQDPahkPkl5H12G3JQgUGsRI OS0AoJMtqax+i/2IPqvKeF1r8WKe3oWs =4fTR -----END PGP SIGNATURE----- --45Z9DzgjV8m4Oswq--
