Tom> With nothing holding back the change, require a c++17 compiler to build gdb. I'm in favor of the change. IIRC the current rule is that gdb shouldn't rely on anything newer than 3 years old (?) and furthermore that the required compiler should either be in the major distros' active LTS releases, or readily installable there. Since you've looked into this, I think we're fine to move forward. However, I do agree with Lancelot that we should do this in GDB 15. That is, hold this patch and land it on trunk shortly after the branch is made. thanks, Tom
