-Particulars

   The standard f2c header file f2c.h must be included by every function 
   generated by running f2c on Fortran source code.  The header f2c.h 
   includes typedefs used to provide a level of indirection in mapping 
   Fortran data types to native C data types.  For example, Fortran
   INTEGER variables are mapped to variables of type integer, where
   integer is a C typedef.  In the standard f2c.h header, the typedef
   integer tranlates to the C type long.  
   
   Because the standard version of f2c.h does not work on all platforms,
   this header file contains two platform-dependent versions of it,
   meant to be selected at build time via precompiler switches.  The
   precompiler switches reference macros defined in SpiceZpl.h to 
   determine for which host platform the code is targeted.  The first
   version of f2c.h, which works on most platforms, is copied directly
   from the standard version of f2c.h.  The second version is intended
   for use on the DEC Alpha running Digital Unix and the Sun/Solaris
   platform using 64 bit mode and running gcc.  On those systems, longs
   occupy 8 bytes, as do doubles.  Because the Fortran standard requires
   that INTEGERS occupy half the storage of DOUBLE PRECISION numbers,
   INTEGERS should be mapped to 4-byte ints rather than 8-byte longs
   on the platforms having 8-byte longs.  In order to achieve this, the
   header f2c.h was transformed using the sed command
   
      sed 's/long //' f2c.h
           
   The high-level structure of this file is then:
   
      # if (    defined(CSPICE_ALPHA_DIGITAL_UNIX    )   \
             || defined(CSPICE_SUN_SOLARIS_64BIT_GCC )  )
      
      
         [ Alpha/Digital Unix and Sun Solaris 64 bit mode/gcc
           version of f2c.h source code ]
         
      # else
      
         [ Standard version of f2c.h source code ]
         
      # endif

-Restrictions

  1) This header file must be updated whenever the f2c processor
     or the f2c libraries libI77 and libF77 are updated.
     
  2) This header may need to be updated to support new platforms.
     The supported platforms at the time of the 31-JAN-1999 release
     are:
     
        ALPHA-DIGITAL-UNIX
        HP
        NEXT
        PC-LINUX
        PC-MS
        SGI-IRIX-N32
        SGI-IRIX-NO2
        SUN-SOLARIS  
   
-Version

   -CSPICE Version 4.0.0, 21-FEB-2006 (NJB)

       Updated to support the PC Linux 64 bit mode/gcc platform.

   -CSPICE Version 3.0.0, 27-JAN-2003 (NJB)

       Updated to support the Sun Solaris 64 bit mode/gcc platform.

   -CSPICE Version 2.0.0, 19-DEC-2001 (NJB)

      Updated to support linking CSPICE into executables that
      also link in objects compiled from Fortran, in particular
      ones that perform Fortran I/O.  To enable this odd mix,
      one defines the  preprocessor flag

         MIX_C_AND_FORTRAN
 
      This macro is undefined by default, since the action it invokes
      is usually not desirable.  See the header 

         f2cMang.h

      for further information.
