Honestly, did these CFLAGS ever work? I don't think GCC knows something |
| 8 |
about a parameter called -02. |

Anyway, I'm using CFLAGS="-O2 -march=pentium-m -pipe" on my Centrino |
| 10 |
laptop for about 2 years now without problems. The architecture |
| 11 |
pentium-m is available from GCC 3.4 on. GCC 3.3 doesn't support it. If |
| 12 |
you use GCC 3.3.x, you should set CFLAGS="-O2 -march=pentium3 -pipe". |

You should also take a look at [1] and [2]. |
