From ce7bbdc38a73702476d10e0c58fc7acab92cb46c Mon Sep 17 00:00:00 2001 From: Joel Galenson Date: Thu, 23 Sep 2021 08:26:53 -0700 Subject: Pass "--extern proc_macro" to rust_proc_macros. This is actually required for some code. Test: Modify the new test so it fails and see it fail. Test: Build crates that fail without it.
