Re:'su' error after cvsup to current 5.1

but the /usr/src/UPDATING says:
 
 There's a  bug in the world build process.  The cross-tools
        are build with the NEW headers, but the OLD libc.a.  This 
        leads to all kinds of problems with the new libc.  A temporary
        workaround is to add
                CFLAGS="-O -pipe -D_OLD_STDIO"
        before building world when upgrading from 4.x to current.  This
        can be removed afterwards.

what shall i do then ?
