 * Revision history:
 *  11-May-96 - Original Version
 *
 * Description:
 *
 * Configuration for the various platforms supported by the compiler.
 * This package is used to configure certain platform-specific options
 * like the -Ofast option set and cache configuration for LNO.
 *
 * This is separate from config_targ because it has a very small set
 * of clients, whereas config_targ.h is included in config.h and hence
 * everywhere.
 *
 * NOTE:  There is an outstanding bug, PV 378171, to base this
 * functionality on an external configuration file.
