 # Clear away all aliases; we do this here rather than in $ENV because the ksh
 # family of shells relies on aliases to implement certain POSIX utilities like
-# fc(1) and type(1)
-unalias -a
+# fc(1) and type(1). Ignore output, as older Zsh seems not to implement this
+# (quelle surprise).
+unalias -a >/dev/null 2>&1
 
 # If ENV is set, source it to get all the POSIX-compatible interactive stuff
 [[ -n $ENV ]] && source "$ENV"
