Macro ambiguity on nightly: std::cfg_match vs crate::utils::macros::cfg_match

[cdata]

It is not currently possible to build safer_ffi on Rust nightly (rustc 1.75.0-nightly (e20cb7702 2023-10-12) at the time of me filing this issue).

The reason appears to be ambiguity between std::cfg_match (an unstable feature introduced in rust-lang/rust#115416) and safer_ffi::utils::macros::cfg_match.

According to the compiler, the ambiguity is introduced due to the wildcard use std::* here:

safer_ffi/src/_lib.rs

Line 514 in 0029467

pub use ::std::{*,
