Log message:
                Optimize setjmp() in space. Use __AVR_3_BYTE_PC__ macro.
                * include/setjmp.h: Reduce size of jmp_buf by 2/1 bytes.
                * libc/stdlib/setjmp.S: Reduce size of jmp_buf by 2/1 bytes. 
Rewrite
                the setjmp() to save flash. Use __AVR_3_BYTE_PC__ to determine 
the
                size of return address (vs EIND register presence). Add common
                assembler pseudos: .type, .size .
                * tests/simulate/regression/20080323-jmpbuf.c: New file.
                * tests/simulate/stdlib/setjmp-1.S: New file.
                * tests/simulate/stdlib/setjmp-2.S: New file.
                * tests/simulate/stdlib/setjmp-3.S: New file.
                * tests/simulate/stdlib/setjmp-4.S: New file.
                * tests/simulate/stdlib/setjmp-5.S: New file.
                * NEWS: Add setjmp() to optimize list.
