* This file implements the name table routines used by the TDF linker.
*
*** Change Log:
* $Log: name-table.c,v $
* Revision 1.1.1.1 1998/01/17 15:57:19 release
* First version to be checked into rolling release.
*
* Revision 1.3 1995/09/22 08:39:29 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 11:46:42 smf
* Performing changes for 'CR94_178.sid+tld-update' - bringing in line with
* OSSG C Coding Standards.
