Previously, we would take a declaration like void f(void) and print it as void f(). That's correct in C++ as far as it goes, but is incorrect in C because that converts the function from having a prototype to one which does not. This turns out to matter for some of our tests that use the pretty printer where we'd like to get rid of the K&R prototypes from the test but can't because the test is checking the pretty printed function signature, as done with the ARCMT tests.
