Multi platform / trace variants

• The environment currently supports:
  • OS/2 (or eCS), as 32-bit executables (OS2 2.0 and up)
  • Windows 32-bit console mode (Win-NT and later)
  • DOS, using 32-bit dos-extended executables
  • Linux 32-bit executable, runs in console and XTERM
• For each of these OS platforms, you get:
  • A 'retail' version, no trace or application trace only
  • A 'trace' version, with trace in application and library
  • A 'debug' version, compiled for use with the debugger
• Meaning you end up with 12 executables ...
