Hi everyone !
With CPUTYPE=p3 in '/etc/make.conf', compilation breaks as such:
[ ... ]
===> usr.bin/uname
===> usr.bin/undo
cc -O -pipe -march=pentium3 -march=pentium3 
-Wsystem-headers -Werror -Wall -W -Wno-unused-parameter

d in this function

Sticking CPUTYPE=i686 instead of CPUTYPE=p3 in '/etc/make.conf' breaks 
compilation with the same double ( -march=* ):
===> usr.bin/undo
cc -O -pipe -march=pentiumpro -march=pentiumpro 

What is the solution to this strangness?
It's some gcc stupidity (generating different warnings if -march is 
tweaked). I guess we can't do much about that problem.

So I've taken out -Werror for now. Please update and try again.
