+         A kernel build should not cause any compiler warnings, and this
+         enables the '-Werror' (for C) and '-Dwarnings' (for Rust) flags
+         to enforce that rule by default. Certain warnings from other tools
+         such as the linker may be upgraded to errors with this option as
+         well.
+
+         However, if you have a new (or very old) compiler or linker with odd
+         and unusual warnings, or you have some architecture with problems,
+         you may need to disable this config option in order to
+         successfully build the kernel.
