State-Changed-Why:
    Confirmed, the warning is only displayed for the
    multi-statement block.
    
    However, what is worse: for 3.3 and present mainline, the
    warning isn't generated _at all_, so this is a regression.
    All this is the same for the C and C++ front ends, by the
    way, so I put it into the more generic "C" category.
