<span class="quote">> I think the bug is still there. I have the following code
>
> char g = 0x8FL;</span >
With -Weverything, I get:
<stdin>:1:10: warning: implicit conversion changes signedness: 'long' to 'char'
[-Wsign-conversion]
char g = 0x8fL;
~ ^~~~~
Anyway, there's no overflow in this code; there's a conversion from 'long' to
'char', which has an implementation-defined result, which for us is a 2s
complement reduction.</pre>
