*  DESCRIPTION:
*
*  Specifies the systems on which the example implementation of the Data
*  Communication I course programming project has been verified to run
*  correctly. Attempts to compile the example implementation on a system not
*  specified in this file will cause an error message to be printed and the
*  compilation to be aborted.
*
*  Systems on which the example implementation has been verified to run
*  correctly:
*  Linux
*  AIX
*  SunOS Solaris
*
*  MODIFICATIONS:   Date    Changes
