+Subject: [PATCH] ignore broken / non-exported macro_rules! macros doctests
+
+This fixes building doctests with Rust 1.62, which now actually runs
+doctests for non-exported macros.
+
+Additionally, doctests that (intentionally or not) create unaligned
+access to struct fields are also disabled. This was always a problem,
+but it started being an error with Rust 1.62.
