Tomasz,

I have not seen this warning despite having used this macro in several
projects. Are you using C++ Tomasz (I only have C projects)?

Follow-up Comment #3, bug #22163 (project avr-libc):

Sorry, but mistake I didn't mention that I'm using avr-g++ compiler. When
using avr-gcc everything is working perfectly, but in g++ the following code
produces warning:
#include util/atomic.h

int main()
{
 volatile int b,a;
 a=0;
 b=0;
 ATOMIC_BLOCK(ATOMIC_RESTORESTATE)
  {
   if(b==0) a++;
  } 
}

I don't know if you consider it as a bug, but it would be great if
ATOMIC_BLOCK could be used in c++.
