(I ended up not needing to use GCC 7 in the end.) Seeing that issue #42392 (=E2=80=9CGCC includes ordering issue? g++: error: 'round' is not a member of 'std'=E2=80=9D) has since been solved, should we close this issue, too? Or are there still reasons to want an adjustment of the gnu-build-system? What do you think, Miguel? --=20 Ricardo
