dbx error ("Executable contains object file compiled on ...")

Hi,

We are trying to run dbx on a core file for which we have the original executable and libs, but not the source / object tree. We have recompiled the objects from the original source, but dbx complains that they were compiled at a different time, and refuses to read them:

Object file: <pathname>/server.o
compiled on: Mon Oct 4 13:50:43 2004
Executable contains object file compiled on: Sun Mar 28 10:19:30 2004
dbx: warning: Object file is not the same one that was linked into executable.
Skipping stabs. (see `help finding-files')

How can we force dbx to ignore the compiled-in date stamps and read the object files?
