  57  * Portability note: The compiler depends upon the host for command-line
  58  * wildcard support - it is not implemented locally. For example:
  59  *
  60  * Linux/Unix systems: Shell expands wildcards automatically.
  61  *
  62  * Windows: The setargv.obj module must be linked in to automatically
  63  * expand wildcards.
