Subject: . Add a script which checks if ${LINUX_BASE}/${WRKDIRPREFIX} is  
 (possibly indirectly) a symbolic link to ${WRKDIRPREFIX}. . Use this script
 in preference to the direct symbolic link check   previously used, as it
 handles indirections which cause the same   problem. . /compat/linux ->
 ${LINUXBASE} in the message output if the check   detects a link.
