The OpenSSL function sk_X509_delete_ptr() resolves through preprocessor
substitution to '(X509 *)sk_delete_ptr()', in which the cast causes the
call to be interpreted as an expression (whose value is not used) rather
than a statement, resulting in the following error under Clang:
...: error: expression result unused [-Werror,-Wunused-value]
Add (VOID) casts to silence the error.
