  10         Description:    defines to hide compiler stuff
  11
  12  1.1   25.06.98 : created from data made by Gunter Nikl
  13  1.2   17.11.99 : added VBCC
  14  1.3   29.02.00 : fixed VBCC REG define
  15  1.4   30.03.00 : fixed SAVEDS for VBCC
  16  1.5   29.07.00 : added #undef statements (needed e.g. for AmiTCP together
  17                   with vbcc)
  18  1.6   19.05.01 : added STACKEXT and Dice stuff
  19  1.7   16.06.01 : added MorphOS specials and VARARGS68K
  20  1.8   21.09.02 : added MorphOS register stuff
  21  1.9   26.09.02 : added OFFSET macro. Thanks Frank Wille for suggestion
  22  1.10  18.10.02 : reverted to old MorphOS-method for GCC
  23  1.11  09.11.02 : added REGARGS define to MorphOS section
  24  1.12  18.01.04 : some adaptions for AmigaOS4 compatibility
  25  1.13  17.02.04 : changed ASM macros to be a simple define and added
  26                   INTERRUPT, CHIP and FAR
  27  1.14  02.03.04 : added UNUSED which can be used to specify a function parameter
  28                   or variable as "unused" which will not cause any compiler warning.
  29  1.15  02.03.04 : added special INLINE define for gcc > 3.0 version
  30  1.17  07.03.04 : changed INLINE definition of gcc <= 2.95.3 to be static aswell.
  31  1.18  21.06.04 : added USED and USED_VAR attribute to allow placing a
  32                   __attribute__((used)) to a function and a variable, taking care of
  33                   different compiler versions.
  34  1.19  04.07.04 : register specification for variables is not supported on MorphOS,
  35                   so we modified the REG() macro accordingly.
  36  1.20  28.02.05 : correct INLINE for VBCC.
  37  1.21  28.02.05 : cleanup __GCC__ case.
