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 twelfth batch of tests being updated (the end may be in
sight soon though).
This fixes a regression introduced in
2b4fa5348ee157b6b1a1af44d0137ca8c7a71573 that caused us to emit
shutdown-time destruction for variables with ARC ownership, using
C++-specific functions that don't exist in C implementations.
