I attempted to convert binutils-gdb to autoconf 2.69 / automake 1.15.1 and it went reasonably well. I don't know very much about gcc, so I could try to do the same in the gcc tree blindly, but I don't feel confident enough to test and validate the changes. So I would avoid it if I can, somebody more used to building gcc could do that part. Could we first rule whether we still need to support combined tree builds? I don't have the necessary background to judge the importance of that feature, but it would basically decide whether I can update the tools used in binutils-gdb in isolation from gcc. Simon
