Renaming subprocedures in a service program

I have been so stupid to use som procedure names as
they are used in examples on the net.

The procedures are the C procedures for teraspace
memory allocations TS_Malloc, TS_Calloc, TS_Realloc
and TS_Free that calls the _C_TS_xxxxx procedures.

Now these subprocedures interfers with other service
programs that I have no controle of.

Is there any smart way to rename the sub-procedures
without loosing the old exported procedures names in the
previous binding directories so old programs doesn't have
to be recompiled unless they uses the subprocedures?
