 No problem.  I'm new at dealing with gcc bugs, so I'm not always sure
 what you're asking for.  I gather you want the output of avr-gcc -E? 
 Assuming so, here it is:
 # 1 "test.c"
 # 1 "<built-in>"
 # 1 "<command line>"
 # 1 "test.c"
 # 1 "/usr/avr/include/io.h" 1 3
 # 20 "/usr/avr/include/io.h" 3
 # 1 "/usr/avr/include/io-avr.h" 1 3
 # 42 "/usr/avr/include/io-avr.h" 3
 # 1 "/usr/avr/include/io8535.h" 1 3
 # 43 "/usr/avr/include/io-avr.h" 2 3

 typedef unsigned char uint8_t;

 typedef long int32_t;
 typedef unsigned long uint32_t;

 int main(void)
 {
         unsigned char t1;
         t1=2;
         t1=(t1+40)%30;
 
         do { if ((__builtin_constant_p((0x17)) && ((0x17)) <= 0x40 + 0 -
 (1))) { if (__builtin_constant_p((0xff)) && ((0xff) == 0)) __asm__
 __volatile__ ( "out %0,__zero_reg__" : : "M" ((uint8_t)(((0x17))-0)) );
 else __asm__ __volatile__ ( "out %1,%0" : : "r" ((uint8_t)((0xff))), "M"
 ((uint8_t)(((0x17))-0)) ); } else (*((volatile uint8_t *)(((0x17)) - 0 +
 0x20))) = (0xff); } while (0);
         do { if ((__builtin_constant_p((0x18)) && ((0x18)) <= 0x40 + 0 -
 (1))) { if (__builtin_constant_p((t1)) && ((t1) == 0)) __asm__
 __volatile__ ( "out %0,__zero_reg__" : : "M" ((uint8_t)(((0x18))-0)) );
 else __asm__ __volatile__ ( "out %1,%0" : : "r" ((uint8_t)((t1))), "M"
 ((uint8_t)(((0x18))-0)) ); } else (*((volatile uint8_t *)(((0x18)) - 0 +
 0x20))) = (t1); } while (0);
 
         return(0);
 }
 
 As far as the assembly output, you just want me to compile the assembly
 and upload the result to my chip and see what happens?  I can do that.
 
 Thanks,
 John Bright
