Actually, this code was generated using the "-i" switch on ld(1).  You usually
used this switch for a reason:  the *&^&%$#@!! program was too big to fit
in memory with combined I & D.  Try re-compiling and re-linking without this
switch (on the 11). If the program will fit with combined I & D space, you
may be able to use it on a vax. If not, you definitely can't.  If you don't
have at least the .o files, bag it.
