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).
(which is ill-formed) with an initializer list. Also, change the
fallback from an assertion to a generic error message, which is far
friendlier. Fixes <rdar://problem/7730948>.
