Hello: I checked the crt0_x.S in the crtx package and find something interesting. In the crt0_x.S the main function is named __main() but not main() normally. But in the normal function we still use main() but not main() i want to know where to address with the symbol __main() by the address of main() in the real application. I look around the crtx package, mk directory and libgendep.so unluckily i don't find it. thanks a lot. Cheng Guanghui
