I updated the wiki page: https://wiki.netbsd.org/pkgsrc/gcc/ The tl;dr is that I would like to head for reduce dependencies of gcc when it doesn't hurt (specifically, enable gcc-inplace-math by default on 4.8 and 4.9), even if this won't help a lot. allow C/C++ versions to differ, realizing that this may be a bad idea, in which case we won't. choose gcc5 as the C++ version for netbsd-7, because 4.8 is too old. Don't use a separate prefix for the bootstrap compiler, and pass a "we are bootstrapping" variable recursively, and omit compiler selection logic. Take a don't-worry-be-happy approach to consistency issues from that, and deal with them if they are troublesome. I think we have a volunteer to produce a patch. Please have a look at the wiki page and either weigh in on listed alternatives or suggest new ones if you think it's broken. I really want to get this in during Q1; now even NetBSD 7 is having trouble.
