      Name, Affiliation, Date: Ali Dasdan, Synopsys, Inc.
  Description of Modification: - Resolved ambiguity with sc_(un)signed.
                               - Merged the code for 64- and 32-bit versions
                                 via the constants in sc_nbdefs.h.
                               - Eliminated redundant file inclusions.
