 Machine Model
 =============
 
    This items pertain to generalizing `g77''s view of the machine model
 to more fully accept whatever the GBE provides it via its configuration.
 
    * Switch to using `REAL_VALUE_TYPE' to represent floating-point
      constants exclusively so the target float format need not be
      required.  This means changing the way `g77' handles
      initialization of aggregate areas having more than one type, such
      as `REAL' and `INTEGER', because currently it initializes them as
      if they were arrays of `char' and uses the bit patterns of the
      constants of the various types in them to determine what to stuff
      in elements of the arrays.
 
    * Rely more and more on back-end info and capabilities, especially
      in the area of constants (where having the `g77' front-end's IL
      just store the appropriate tree nodes containing constants might
      be best).
 
    * Suite of C and Fortran programs that a user/administrator can run
      on a machine to help determine the configuration for `g77' before
      building and help determine if the compiler works (especially with
      whatever libraries are installed) after building.
