clang 3.9 add this warning to rightly flag undefined
behavior, we relegate this to be just a warning instead
of error and keep the behavior as it was. Right fix would
be to not pass enum to the function with variadic arguments
as last named argument
Fixes errors like
ocsp.c:2220:22: error: passing an object that undergoes default argument promotion to 'va_start' has undefined behavior [-Werror,-Wvarargs]
va_start(ap, responseType0);
^
ocsp.c:2200:43: note: parameter of type 'SECOidTag' is declared here
SECOidTag responseType0, ...)
