Good news! R-2.3.1 beta compiled and installed successfully with both |
| 2 |
3.4.5 and 4.1.1!! I also recompiled most of the library packages. I |
| 3 |
haven't seen any failures that would have been compiler-related, so I'm |
| 4 |
tempted to leave gcc 4.1.1 as the default for a while. |

|

I don't have much more Fortran-based software, but I do think it's worth |
| 7 |
recompiling blas-atlas and lapack-atlas with gcc 4.1.1. |
