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 fifth batch of tests being updated (there are a significant number of other tests left to be updated). Note, the behavior of -ast-print is broken. It prints functions with a prototype (void) as if they have no prototype () in C. Some tests need to disable strict prototype checking when recompiling the results of an -ast-print invocation.
