  11         Description:    defines to hide compiler stuff
  12
  13  1.1   25.06.98 : created from data made by Gunter Nikl
  14  1.2   17.11.99 : added VBCC
  15  1.3   29.02.00 : fixed VBCC REG define
  16  1.4   30.03.00 : fixed SAVEDS for VBCC
  17  1.5   29.07.00 : added #undef statements (needed e.g. for AmiTCP together
  18                   with vbcc)
  19  1.6   19.05.01 : added STACKEXT and Dice stuff
  20  1.7   16.06.01 : added MorphOS specials and VARARGS68K
  21  1.8   21.09.02 : added MorphOS register stuff
  22  1.9   26.09.02 : added OFFSET macro. Thanks Frank Wille for suggestion
  23  1.10  18.10.02 : reverted to old MorphOS-method for GCC
  24  1.11  09.11.02 : added REGARGS define to MorphOS section
  25  1.12  18.01.04 : some adaptions for AmigaOS4 compatibility
  26  1.13  17.02.04 : changed ASM macros to be a simple define and added
  27                   INTERRUPT, CHIP and FAR
  28  1.14  02.03.04 : added UNUSED which can be used to specify a function parameter
  29                   or variable as "unused" which will not cause any compiler warning.
  30  1.15  02.03.04 : added special INLINE define for gcc > 3.0 version
  31  1.17  07.03.04 : changed INLINE definition of gcc <= 2.95.3 to be static aswell.
  32  1.18  21.06.04 : added USED and USED_VAR attribute to allow placing a
  33                   __attribute__((used)) to a function and a variable, taking care of
  34                   different compiler versions.
  35  1.19  04.07.04 : register specification for variables is not supported on MorphOS,
  36                   so we modified the REG() macro accordingly.
  37  1.20  28.02.05 : correct INLINE for VBCC.
  38  1.21  28.02.05 : cleanup __GCC__ case.
  39  1.22  16.05.05 : changed the vbcc/REG() macro.
  40                   added missing vbcc/VARARGS68K define.
  41                   moved morphos SDI_EmulLib Stuff into compilers.h. I know it's not
  42                   compiler specific,  (Guido Mersmann)
  43  1.23  30.04.06 : modified to get it compatible to AROS. (Guido Mersmann)
  44  1.24  06.05.06 : __linearvarargs is only valid for vbcc and PPC, so I moved VARARGS68K
  45                   to prevent problems with 68K and i86 targets. (Guido Mersmann)
  46  1.25  21.06.07 : added NEAR to be usable for __near specification for SAS/C
  47  1.26  14.10.07 : added DEPRECATED macro which defaults to __attribute__((deprecated))
  48                   for GCC compiles.
  49  1.27  20.03.09 : applied some changes and fixes to get the header more usable
  50                   for an AROS compilation. (Pavel Fedin)
  51  1.28  25.03.09 : added missing IPTR definition to make SDI_compiler.h more compatible
  52                   to AROS. (Pavel Fedin)
  53  1.29  25.03.09 : fixed the IPTR definition and also the use of the __M68000__ define.
