initdb failure in CVS

I am seeing the following failure of initdb in CVS:The files belonging to this database system will be owned by user
"postgres".Thisuser must also own the server process.The database cluster will be initialized with locale C.creating

   FATAL:  invalid value for parameter "client_encoding": ""
initdb: child process exited with exit code 1initdb: failedinitdb: removing data directory "/u/pg/data"

The problem seems to be related to a commit made to initdb a few days
ago.
revision 1.24date: 2004/05/05 16:09:31;  author: tgl;  state: Exp;  lines: +23 -2Use a more portable technique for
unsettingenvironment variables,and unset PGCLIENTENCODING to prevent backend from dying if it's setto something
incompatiblewith the -E option.
 

I don't have any encoding set in my system.
