Bug ID: 113283 Summary: missing C++26 freestanding headers. Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: unlvsur at live dot com Target Milestone: --- C++26 adds things like cerrno to be freestanding. I do not know how you are going to support that. libcxx wants to forward the errno.h to the compiler side.
