A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the tenth batch of tests being updated (there are a significant number of other tests left to be updated).
