Well, I've gcc 3.2.3 on my 3/60 and it came prebuilt, though I can't recall where did it come from.
It turned out that it's pretty straightforward to build recent software with it, at least compared, say, to much newer HP-UX
I also have a small but valueable collection of gnu utils, perl, sudo, pdksh, openssh, even clisp, and probable more, prebuilt or built locally by me.
I guess it's worth to consider to gather a repository as Sun-3 software collection sites tend to die out.
