The cdefs.h header on stable/14 and stable/13 are quite behind the one on main and stable/15. This causes issues like the above, when __noexcept, __deprecated1 and others are not defined during the legacy stage, and it picks up _some_ headers from the host system, and others from the location installed by tools/build/Makefile. > > I think I will rollback the MFCs for now, until I can figure out a solution. Ideally we would not have to copy cdefs.h for this bootstrap part, but that leads to other issues. As an alternative solution, I have MFC'd support for __noexcept, __deprecated, and __deprecated1 to stable/14 and stable/13, with a small additional patch to stable/13. I believe both branches should now build fine on main. -Dimitryhome | help
