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 fourth batch of tests being updated (there are a significant
number of other tests left to be updated).
-performSelector: and friends return a value that is boxed as an Objective-C
pointer. Sometimes it is an Objective-C pointer, sometimes it isn't.
Some clients may wish to silence this warning based on calling
this method.
