#if ARCH == ARM  
// ARM code 
#endif 
 
#if ARCH == ix86 
// Intel x86 code 
#endif 

I might be off base, but I think c preprocessor comparasions can only work with integers. Take the following the example:

#include <stdio.h> 
int main() { 
 
#if ARCH == ARM 
  printf("Arch is ARM \n"); 
#else 
  printf("Arch is something else \n") 
#endif 
return 0; 
} 

Compiling and running with:
1) gcc -DARCH=x86 test.c -o test outputs "Arch is ARM"
2) gcc -DARCH=ARM test.c -o test outputs "Arch is ARM"

The code works as expected with the following:

#include <stdio.h> 
int main() { 
 
#if ARCH == 1 
  printf("Arch is ARM \n"); 
#else 
  printf("Arch is something else \n") 
#endif 
return 0; 
} 

1) gcc -DARCH=1 test.c -o test outputs "Arch is ARM"
2) gcc -DARCH=0 test.c -o test outputs "Arch is something else"

Thanks,
