One (~x86) LXDE system completed the switch with no problem, the other (~amd64) built all except two packaged (sdlmame and torcs) which did not build with gcc-7.2 even before the switch to 17.0.
Gentoo devs and arch testers did a good job as usual. I'll do the switch on the Gnome system in the next days but up to now I can say that the switch to 17.0 is a _lot_ less painful than switching major compiler version. raffaele
