  Interface macros for ASM subroutines for GCC and SAS/C

  syntax:
   ASM SAVEDS int some_asm_subroutine(   
                         ASMR(d3) unsigned int   some_data    ASMREG(d3),
                         ASMR(a0) unsigned char *some_address ASMREG(a0) 
			             );

  Reason for the double spec of An/Dn: some compilers (SAS) require the register
  on the left hand side, gcc on the right hand side. I wanted to avoid a big macro
  for the whole argument and moved the stuff into two macros per argument.
