If so, this would require some bugreport to gcc team?
The text says too: "Other native compiler versions may work but this is not guaranteed and will typically fail with hard to understand compilation errors during the build." I tried last year to build the tools "--with_ada" on Ubuntu, OpenSUSE, Fedora, AlmaLinux and Debian. Moreover, I tried all versions of GNAT each of the OS offered "normal" users to install. Only GNAT 10 worked for me. Nothing else. The text in the chapter your cited can be understood this way: Compiling ADA with a native compiler of the same version will work. If the native compiler has a higher version it, is rather unlikely to work. If the native compiler has a lower version, it may work or not. So, I do not think you can file a bug with GCC.
