From 158a3b72118a4dab7e7bf2d89afbab9b96eddc1c Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Mon, 24 Nov 2025 16:18:22 +0100 Subject: rust: proc-macro2: enable support in kbuild With all the new files in place and ready from the new crate, enable the support for it in the build system. `proc_macro_byte_character` and `proc_macro_c_str_literals` were stabilized in Rust 1.79.0 [1] and were implemented earlier than our minimum Rust version (1.78) [2][3]. Thus just enable them instead of using the `cfg` that `proc-macro2` uses to emulate them in older compilers. In addition, skip formatting for this vendored crate and take the chance to add a comment mentioning this.
