/* RCS $Id: rmprq.c,v 1.2 2002-10-11 13:42:47 waratah Exp $
--
-- SYNOPSIS
-- Remove prerequisites code.
--
-- DESCRIPTION
-- This code is different for DOS and for UNIX and parallel make
-- architectures since the parallel case requires the rm's to be
-- run in parallel, whereas DOS guarantees to run them sequentially.
