+       Add refcount builtin.
+       * modules/load.c (refcount): New builtin.
+       (m4modules): Use correct type.
+       * doc/m4.texinfo (Refcount): New section.
+       * m4/m4private.h (struct m4_module): Add refcount member.
+       (m4_module_refcount) [NDEBUG]: Add faster accessor macro.
+       * m4/module.c (m4_module_load): Add symbols to table on first
+       load by m4, regardless of other libltdl loads of same module.
+       (m4_module_refcount): Use new struct member, rather than relying
+       on libltdl count which might be inflated by unrelated loads.
+       (m4__module_interface): Optimize.
+       (m4__module_next, m4__module_find): Avoid assertions that could
+       trigger with unrelated libltdl loads.
+       (m4__module_open): Track m4 load count.
+       (m4__module_exit): Only unload what m4 loaded.
+       (module_remove): Track m4 unloads.
+       * NEWS: Document new builtin.
+
        More conversion to m4_module*.
        * src/freeze.c (produce_module_dump, dump_symbol_CB)
