Florian Albrechtskirchinger f208a9c19b Fix C++20/gcc-12 issues (Part 1) (#3379) ... * 🔧 use proper GCC binary * 🔧 add more GCC warning flags * ⚗️ try fix from https://github.com/nlohmann/json/issues/3138#issuecomment-1015562666 * Fix custom allocator test build failures (C++20) Allocator tests fail to compile in C++20 mode with clang+MS STL due to missing copy constructors. * Fix test build failures due to missing noexcept (gcc-12) * alt_string has multiple member functions that should be marked noexcept. * nlohmann::ordered_map constructors can be noexcept. Compilation failures result from the warning flag -Werror=noexcept and gcc-12. * Disable broken comparison tests in C++20 mode Co-authored-by: Niels Lohmann <mail@nlohmann.me>		2022-03-07 22:19:28 +01:00
