By setting CPUTYPE=p[234] excplicitly in /etc/make.conf you'll get the build failure in XFree86-4-Server because bsd.cpu.mk will set excplicit -march, not -mcpu. But the build error happens _only_ if one sets CPUTYPE=p[234] and not in case CPUTYPE=i686, the latter sets -march=pentiumpro, not -march=pentium[234]. Hope this is all clear now and sorry about confusion, english isn't my native tongue after all. -- Vallo Kallaste kalts@estpak.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
