/*** unit-entry.c --- Unit set table entry ADT.
*
** Author: Steve Folkes <smf@hermes.mod.uk>
*
*** Commentary:
*
* This file implements the unit set table entry routines used by the TDF
* linker.
*
*** Change Log:
* $Log: unit-entry.c,v $
* Revision 1.1.1.1 1998/01/17 15:57:20 release
* First version to be checked into rolling release.
*
* Revision 1.3 1995/09/22 08:39:43 smf
* Fixed problems with incomplete structures (to shut "tcc" up).
* Fixed some problems in "name-key.c" (no real problems, but rewritten to
* reduce the warnings that were output by "tcc" and "gcc").
* Fixed bug CR95_354.tld-common-id-problem (library capsules could be loaded
* more than once).
*
* Revision 1.2 1994/12/12 11:47:05 smf
* Performing changes for 'CR94_178.sid+tld-update' - bringing in line with
* OSSG C Coding Standards.
*
* Revision 1.1.1.1 1994/07/25 16:03:40 smf
* Initial import of TDF linker 3.5 non shared files.
*
