Stephan Bergmann 106ea87205 Remove _TYPED suffix from tools/link.hxx macros 
...which was introduced with 3ead3ad52f "Gradually
typed Link" to distinguish the new, typed versions from the old, untyped ones,
but is no longer necessary since 382eb1a23c
"remove untyped Link<>" removed the old versions.
