Yes, you the rights. I know about arithmetic on void pointers, but I expected
type-conversion operator will make it possible to deceive the compiler. For
example, Borland C++ 5.02 and Keil uVision-2 process the following code
successfully and do what I need:
void func(void *dest, void *src, int size) {
while (size--) *((char*)dest)++ = *((char*)src)++;
}
But this is erroneous, because standard speaks: "A cast does not yield
lvalue". This is why nor increment, nor assignments does not work in this
case. These compilers have strange idea about the precedence of the
operators. Therefore, gcc and sdcc more correct.
Thank you all.
