  28. * 07-31-90 SBM added ((void)0) to NDEBUG definition, now ANSI
  29. * 08-20-91 JCR C++ and ANSI naming
  30. * 08-26-92 GJF Function calling type and variable type macros.
  31. * 09-25-92 SRW Don't use ? in assert macro to keep CFRONT happy.

  39. * 02-14-95 CFW Clean up Mac merge.
  40. * 03-02-95 CFW Removed _INC_ASSERT. According to ANSI, must be able
