   4    file named g2c.h.in.  This process sets up the appropriate types,
   5    defines the appropriate macros, and so on.  The resulting g2c.h file
   6    is used to build g77's copy of libf2c, named libg2c, and also can
   7    be used when compiling C code produced by f2c to link the resulting
   8    object file(s) with those produced by the same version of g77 that
   9    produced this file, allowing inter-operability of f2c-compiled and
  10    g77-compiled code.  */
