Hi Joerg,
I didn't missed to add #include <avr/io.h> in my file. Sorry I didn't
attach the all code because it's too long.
I have no problem before when I compile with WinAVR2004 and WinAVR2005, this
only happen with WinAVR2007 where the compiler can generate sbi and cbi
command for PORTC (no problem for the other ports)
I'm still checking where is the problem now.
Thanks,
Regards
Andi

This is the code:
Sending compilable code makes us better trust you not doing any
copy&paste errors. Let's hope all that you left out is the #include
<avr/io.h>.
the LST generated file:
I never understand why people are so fond of that unreadable
disassembly stuff. It also appears your copy&paste left out some
single letters there.
Here's the assembly code the compiler generates when I add the
<avr/io.h> include line, and compile it for an ATmega8 with -Os:
..global InitLoad
.type InitLoad, @function
InitLoad:
/* prologue: frame size=0 */
/* prologue end (size=0) */
sbi 52-0x20,2
cbi 53-0x20,2
/* epilogue: frame size=0 */
ret
/* epilogue end (size=1) */
/* function InitLoad size 3 (2) */
.size InitLoad, .-InitLoad
..global InitPABX
.type InitPABX, @function
InitPABX:
/* prologue: frame size=0 */
/* prologue end (size=0) */
sbi 52-0x20,1
sbi 49-0x20,4
cbi 53-0x20,1
cbi 50-0x20,4
/* epilogue: frame size=0 */
ret
/* epilogue end (size=1) */
/* function InitPABX size 5 (4) */
That looks pretty fine to me. If I compile it into a .o file, and
just disassemble it (without the annoying attempt to intersperse it
with what the disassembler believes were the related source code),
I get:
Disassembly of section .text:
00000000 <InitLoad>:
0: a2 9a sbi 0x14, 2 ; 20
2: aa 98 cbi 0x15, 2 ; 21
4: 08 95 ret
00000006 <InitPABX>:
6: a1 9a sbi 0x14, 1 ; 20
8: 8c 9a sbi 0x11, 4 ; 17
a: a9 98 cbi 0x15, 1 ; 21
c: 94 98 cbi 0x12, 4 ; 18
e: 08 95 ret
Again, all looks fine to me.

Never trust an operating system you don't have sources for. ;-)
