Hi both,

Glad to be of help! Overall, this looks like a variation of what we had
in the past especially when clang switched to C++11 by default and a
lot of ports broke.

Specifically in these 2 cases in case it helps:
* games/eboard seems to be failing because it defines an enum called
`variant` while also doing `using namespace std`, which breaks because
C++17 has std::variant.
* net-p2p/amule uses the `register` keyword in a bunch of places
(including some autogenerated flex/bison ones that are part of the
tree), and it has been removed/deprecated in C++17.

As for a PORTREVISION bump: it _could_ be the case that the generated
files differ now, as in the past the default standard was gnu++14
rather than c++11. For leaf ports like these two I don't think the
difference really matters, but I've been semi-abstent for so long that
portmgr@ or someone more active may have a better guideline.
