I've just built 4.3.1 with binutils 2.18.

It's not ideal that one has to have very specific compiler versions, which use a particular linker and assembler. Given Sun distribute gcc, if possible it would be nice for Sage to build with that. Of course, the Sun compiler suite would be preferable, as that is more fixed and you can just say to someone to use it. Experience tells me the goal posts don't move as much as they do with gcc. I've just built gcc-4.3.1 (the latest) from source code, but it is not a trivual process. Attempting to compile a recent gcc with an old gcc is likely to fail, as is trying to compile gcc with Sun's compiler. The only way I could build the latest gcc was to compile a later version than what I had, then use this to compile the latest version. I think I went 1) 4.0.2 (with Sun linker) 2) 4.0.3 (with latest gnu binutils) 3) 4.2.2 (with latest gnu binutils) 4) 4.3.1 (the latest gcc, with the latest binutils). If at all possible, this sort of thing should be avoided, as it makes it difficult for someone to build software. The fact the development tools on Solaris can be a bit of a mess is probably one reason that places like Blastwave and Sunfreeware don't tend to update gcc much.
