The following statement is the result of a macro expansion
(hence all the extra parenthesis). gcc's giving me a new
warning about using a casted lvalue. I don't see where there is
a casted lvalue here. The rhs of the assigment is an rvalue, so
I'll ignore that. port is casted, but it's an rvalue at this
point. Once it's dereferenced it's an lvalue, but there's no
further casting after that. What's gone wrong here?
const void* src;
(*((volatile uint16_t*)(port)) = (*((uint16_t *) src)++));
