/* Test predefined Macros to determine compiler type, and hopefully 
   selectively use fast in-line assembler (or other compiler specific
   optimisations. Note I am unsure of Microsoft version numbers. So I 
   suspect are Microsoft.

   Note: It seems to be impossible to get the 16-bit Microsoft compiler
   to allow inline 32-bit op-codes. So I suspect that INLINE_ASM == 2 will
   never work with it. Pity. 

#define INLINE_ASM 1    -> generates 8086 inline assembly
#define INLINE_ASM 2    -> generates mixed 8086 & 80386 inline assembly,
                           so you can get some benefit while running in a 
                           16-bit environment on 32-bit hardware (DOS, Windows
                           3.1...)
#define INLINE_ASM 3    -> generate true 80386 inline assembly - (Using DOS 
                           extender, Windows '95/Windows NT)
                           Actually optimised for Pentium

#define INLINE_ASM 4    -> 80386 code in the GNU style (for (DJGPP)

Small, medium, compact and large memory models are supported for the
first two of the above.
