https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106852 --- Comment #4 from Boris Kolpackov --- FWIW, this project contains a subset of module interface files that (reportedly) can be used to build a (probably incomplete) `std` module with `libstdc++` using Clang (the README says it requires `libc++` but I've confirmed with the author it is tested with both `libstdc++` and `libc++`): https://github.com/alibaba/async_simple/tree/CXX20Modules/third_party_module/stdmodules I am putting it out there in case someone is looking for a potential starting point: maybe we could get going using Clang while GCC's modules support is being worked into shape (and I am glad to see there was some progress on this front for 14).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106852 Jiang An changed: What|Removed |Added CC||de34 at live dot cn --- Comment #1 from Jiang An --- Should std.compat provide 3-argument hypot overloads in the global namespace? MSVC STL's std.compat intentionally doesn't provide them in the global namespace (https://github.com/microsoft/STL/pull/3108). I think this possibly makes sense, and we may submit an LWG issue to exclude them from the global namespace. However, for libstdc++, such exclusion would slightly complicate the implementation.
