Attached is a patch to enable using the 102nd key as Compose/Multi_key. The rationale for this is that one may be in a country with a "European"-style keyboard, but still use a 101-keys layout - for instance the U.S. - and prefer to enter accented characters using the Compose/Multi_key instead of through dead keys. The 102nd key would be otherwise unused by the layout. As a bonus, it is also located close to where the Compose key originally used to be on DEC keyboards of yore.
