You are best off just using --enable-proc-opt. I think that there is 
something wrong with the way configure determines the architecture 
although I cannot see what it does wrong. I used --arch=i686 on my Intel 
Core 2 Duo motherboard, and then noticed that make was using 
'-march=k6'!....I added the cpu_type 'core2' to the enumerated types in 
configure at about line 700, and it then ran nicely.

Minutes later, configure on my Intel Pentium4 desktop choked on 
--arch=permtium4 and I had to revert to --enable-proc-opt...

I have NO idea why or what!
