march for my CPU
Hello, guys !
I tried to compile PHP on one of my servers (LAMP). Everything worked fine only that I tried to set my march to pentium4 and it did not accepted it. It told me that it is a x86_64 architecture and pentium4 is not supported (I don't remember the exact error, but this was the ideea). Anyway, I would like to know what march should I set in compile-time.
uname -a looks like this:
and my cat /proc/cpuinfo looks like this:
So, what should I put as march when I compile ? 
Thanks in advance for your time and answers.
