I just compiled about 250 packages from Fedora Rawhide with compiler flag -Wold-style-definition. The average number of occurrences of the warning message per package is current running around 30. Admittedly a small sample of the 8,000 or so packages in Fedora Rawhide, but current estimates are about 240,000 old style function definitions for that distribution. It might well be worthwhile putting -Wold-style-definition into -Wextra for a year or so and see how we get on.
