Re: Volatile MEMs in statement expressions and functions inlined as trees

Hmm...  So, if I have:

  volatile int c;

  (volatile char)c;

Do I read a char or an int from c's address?

Does it matter if one of the `volatile's is ommitted?

And now, an easy question: is this yet another GCC extension whose
consequences were not fully thought-out in advance? :-)
