// Note:  other, more generic, symbols (e.g., IRIX) are also acceptable,
//   but are not recommended, as they are less specific and hence admit
//   the possibility of inaccuracy if used in an untested environment.
//   These generic symbols typically consist of the OS name, or the OS
//   name followed by the compiler name (separated by an underscore).

//
// History:
//   05-Feb-1997  WEB  Initial draft w/ native & gcc under IRIX
//   07-Feb-1997  WEB  Add Borland C++ 5.0 under NT 4.0
//   08-Feb-1997  WEB  Add AIX
//   11-Feb-1997  WEB  Add DCC & CC's under IRIX
//   14-Feb-1997  WEB  Restructure the testbed environment
//   18-Feb-1997  WEB  Add SC 4.0 under SOLARIS 2.4
//   21-Feb-1997  WEB  Add MicroSoft Visual C++ 4.0 under NT 4.0
//   16-Apr-1997  WEB  Code review by FPCLTF; add internal guard;
//     general issues re environment identification yet to be resolved
//   10-Sep-1997  WEB  Add gcc 2.7.2.1 under IRIX 6.2
//   26-Nov-1997  WEB  Merge into ZMftUtility package; add tests for
//     generic OS and OS-compiler combinations, keeping the previous
//     more-detailed version-number orientation, as well
//   02-Dec-1997  WEB  Made the #undef's conditional upon need; update
//     documentation; add KAI under LINUX & IRIX; other cleanup
//   14-Jan-1998  WEB  Add gcc 2.7.2.3 under OSF/1 (DEC Alpha) per
//     request of P Schemitz, Univ of Karlsruhe
//   02-Mar-1998  WEB  Version 2.0:  employ typedef's
//   14-Jan-1998  WEB  Add KAI 3.2 under SOLARIS 2.6 per Leo Michelotti
//   15-Jun-1998  WEB  Add namespace support
//   10-Nov-1998  WEB  Add KAI 3.3 under IRIX 6.2; remove IRIX4.0.5F
//   19-Feb-1999  WEB  Add generic OSF1; minor cleanups
//   10-Mar-2000  WEB  Add generic SunOS
//   23-Jun-2000  WEB  Add generic IRIX6, IRIX6_2, IRIX6_5
