gcc40 fails to build on Snow Leopard

[takeshi@…]

My Mac Book Pro have Core 2 Duo but boots into the 32-bit kernel mode.

Seems to have a problem at link time.

Successful build of gcc40 would give hints for g95, which needs to build libgcc.a and libbackend.a.

I added the patches to FSF gcc 4.4 branch and trunk to compile on darwin10. These were never back ported to the earlier FSF gcc releases. The FSF gcc 4.2 branch is now depreciated and the effort to backport all those changes to FSF gcc 4.3 branch didn't seem worth the effort. In fink, I marked their gcc42 and gcc43 packages as Distribution: 10.4,10.5 so that they don't get built on 10.6. MacPorts needs to do something like this. You can compile the gcc44 package in MacPorts on 10.6 if you use my proposed update in ticket 21341.

Thank you for your comments. I was thinking that I might have to encourage Andy Vault to use newer gcc. But XCode comes with gcc4.0 and gcc4.2 so Apple gcc should be able to build. Among maintainers of scitech packages we agree to use gcc43 to the default. If gcc42 and gcc43 will be deprecated in MacPorts, we have to change the agreement and move forward to use gcc44 as default.
