  Revision 1.12  2003-12-01 18:43:32  peter
    * s128real type is not compatible with s80real

  Revision 1.11  2003/11/28 13:09:07  mazen
  + defintion of ts128real
  + globtype is needed in interface uses clause

  Revision 1.10  2003/11/07 15:58:33  florian
    * Florian's culmutative nr. 1; contains:
      - invalid calling conventions for a certain cpu are rejected
      - arm softfloat calling conventions
      - -Sp for cpu dependend code generation
      - several arm fixes
      - remaining code for value open array paras on heap

  Revision 1.9  2003/09/03 15:55:01  peter
    * NEWRA branch merged

  Revision 1.8  2003/06/17 16:35:42  peter
    * JMP_BUF_SIZE changed to 4 to remove Alloctemp warnings

  Revision 1.7  2003/05/23 22:33:48  florian
    * fix some small flaws which prevent sparc linux system unit from compiling
    * some reformatting done

  Revision 1.6  2002/11/16 20:07:57  florian
    * made target_cpu_name lowercase

  Revision 1.5  2002/10/16 12:36:54  mazen
  * patch of Carl Eric added
