Bill asserts that I broke his code with the 31DEC03 release and has not 
fixed it.  I am now working in the heart of the imaging and will 
probably make more troubles.  Bill and others (JIVE, GMRT) seem to think 
that AIPS is unchanging and so they depend on it without involving me. 
That is not a good idea and I will not be responsible.

You need to make link files to point at the libraries under a new name 
and change your make file so that the second occurrence of APLSUB and 
APLLINUX are instead the new names.  Intel insists on dropping any 
"duplicates" in the link list even though it does not recurse in its 
search.  Our version is one of the few that does not have this bug.

cd $LIBR
ln -s APLSUB APLJUNK
ln -s APLLINUX LINJUNK

then edit the make to change the 2nd ref to APLSUB/SUBLIB to 
APLJUNK/SUBLIB and 2nd ref of APLLINUX/SUBLIB to LINJUNK/SUBLIB.  The 
$SYSLOCAL file LIBR.DAT is the aips-standard place to change this as well.
