If you have a P4 you should use the i686 stage. You can recompile everything afterwords to optimize for your processor, -march=pentium4. |

You had better use i686 stage with this variables.
| Code: | CFLAGS="-march=i686 -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

Yes, use the i686 stage, but you can optimize a bit more for your processor. Take a look at this page, it has listings for many intel chips and the corresponding CFLAGS:

Make sure you correctly identify your processor by checking `cat /proc/cpuinfo` before making a selection. |
