Is gcc 10 fine in general?
On an old machine (note to self: upgrade it) linux `g++ (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0` works here (this PR builds and runs fine).
I really don't know what is wrong with the mingw build at this point.
Me neither. https://github.com/geany/infrastructure/pull/10 fixes the first problem with the Docker mingw64 image build. Since this is done now, I will test this PR on a real Windows system to see if it compiles there (I guess yes).
Adding the gcc/g++ version is easy, maybe also the libstdc++ version as well.
👍 Not aware of anything else.
Will do later.
