* `dev-libs/boost` & `dev-libs/boost-static` - a hacky way to get static Boost libraries using a second ebuild, not all USE flags are tested!
* `sci-electronics/magic` - updated to a newer version and set `-std=gnu89` permanently, used to fail to compile because of `termio.h` and old-style function declarations mixed with C99-style comments.
* `sci-electronics/opensta` - new ebuild, the stable version needs SWIG 3.0, which is no longer available in the Gentoo repo, the live ebuild merges fine.
+* `sci-libs/lemon` - updated for C++20 compatibility.
* `sci-mathematics/cudd` - building documentation fails with a modern C++ compiler, this ebuild just skips the docs.
