Import C++ Standard Template Library You can now use the hardest fastest and most dangerous language there is with Cosmopolitan. So far about 75% of LLVM libcxx has been added. A few breaking changes needed to be made to help this go smoothly. - Rename nothrow to dontthrow - Rename nodiscard to dontdiscard - Add some libm functions, e.g. lgamma, nan, etc. - Change intmax_t from int128 to int64 like everything else - Introduce %jjd formatting directive for int128_t - Introduce strtoi128(), strtou128(), etc. - Rename bsrmax() to bsr128() Some of the templates that should be working currently are std::vector, std::string, std::map, std::set, std::deque, etc. 2022-03-22 12:51:41 +00:00			`#ifndef COSMOPOLITAN_LIBC_ISYSTEM_FEATURES_H_`
