Last change on this file since 1703f72 was c79a047, checked in by Anders Kaseorg <andersk@mit.edu>, 12 years ago
Correctly prototype functions with no parameters as foo(void), not foo(). foo() is a deprecated old-style prototype for a function that takes any arguments. Specifying foo(void) catches more bugs. Signed-off-by: Anders Kaseorg <andersk@mit.edu>
