Maybe ... it wasn't entirely clear to me from the discussion, which was |

relative to Atlas and (shudder) Fedora Core 4, where GCC 4 is the default. |

In the case of Atlas, Clint Whaley tried a couple of tests with GCC 4 |
14 |
and discovered on some pretty pure and simple scientific code, GCC 4 was |
15 |
quite a bit slower than 3.4 on an x86-32. He says, "stick with 3.4 for |
16 |
Atlas until 4 gets better". I don't have access to an AMD 64-bit machine |
17 |
and I don't have (legitimate, anyhow) access to an Intel x86-64 machine. |
18 |
So for now, anyhow, I can wait until all 10,000+ packages in Portage |
19 |
compile and test out with GCC 4 <ducking> |
