  10 //   13 Jun 01 report_exception() made inline. (John Maddock, Jesse Jones)
  11 //   26 Feb 01 Numerous changes suggested during formal review. (Beman)
  12 //   25 Jan 01 catch_exceptions.hpp code factored out of cpp_main.cpp.
  13 //   22 Jan 01 Remove test_tools dependencies to reduce coupling.
