entry-point: start (notice this symbol name is valid on asm-level only !)

hooks for c:

/* called at the beginning of main */
void __main(void){
}
/* called if program terminates */
void exit(int){
}
void atexit(){
}

additionally for cpp (thanx to emanuel, tubooboo@ngine.de, www.ngine.de):

extern "C" {

    void *__builtin_new(int size) {
            return malloc(size);
    }

    void __builtin_delete(void *ptr) {
            free(ptr);
    }

} // end extern "C"
