Hi, I was reading about CFLAGS to set it best for my system. I've
searched for the -mcpu value that fits my Intel Celeron 2.00GHz
processor but couldn't find it. By looking cpu family and model from <a href="http://gentoo-wiki.com/Safe_Cflags">Gentoo Wiki Safe Cflags article</a> &quot;pentium4&quot; value seems the best but i've a celeron?. In make.conf
 file its default value is i686:<br>
<br>
CFLAGS=&quot;-O2 -mcpu=i686 -pipe&quot;<br>
CHOST=&quot;i686-pc-linux-gnu&quot;<br>
CXXFLAGS=&quot;${CFLAGS}&quot;<br>
MAKEOPTS=&quot;-j2&quot;<br>
<br>
Please give me a hand, which value should i use for my processor?<br>
