cde/src/cmd/ksh93/include/name.h
Martijn Dekker fb8719fe1d Remove more unused stuff 
A systematic grepping of the extern function definitions in
src/cmd/ksh93/include/*.h revealed more functions that either don't
exist or are not used anywhere. Some of them have never seen any
use in the entire ksh93-history repo (i.e. since 1995). They were
also all undocumented, so it's unlikely third-party custom
built-ins rely on them.
