+%package plugin-annobin
+Summary: The annobin plugin for gcc, built by the installed version of gcc
+Requires: gcc = %{version}-%{release}
+# Starting with release 10.01 annobin fixed a bug in its configure scripts
+# which prevented them from working with a built but not installed compiler
+BuildRequires: annobin >= 10.01
+# Starting with release  9.93 annobin-plugin-gcc puts a copy of the sources
+# in /usr/src/annobin
+# FIXME: Currently the annobin-plugin-gcc subpackage only exists in Fedora.
+# For RHEL-9 the annobin package does everything.
+# BuildRequires: annobin-plugin-gcc
+# Needed in order to be able to decompress the annobin source tarball.
+BuildRequires: xz
+
+%description plugin-annobin
+This package adds a version of the annobin plugin for gcc.  This version
+of the plugin is explicitly built by the same version of gcc that is installed
+so that there cannot be any synchronization problems.
