# This shim is a workaround for the missing `m4` in Xcode CLT 15.3.
# It can be removed after Apple provides a new CLT with a fix for FB13679972.
# See https://github.com/Homebrew/homebrew-core/issues/165388
# HOMEBREW_LIBRARY is set by bin/brew
# HOMEBREW_DEVELOPER_DIR is set by extend/ENV/super.rb
