Yes I know and it was what I meant to say. By setting CPUTYPE=p
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
and not in case CPUTYPE=i686, the latter sets -march=pentiumpro, not
-march=pentium. Hope this is all clear now and sorry about
confusion, english isn't my native tongue after all.
