bool wrappers for unnamed parameters don't work #131

Closed ian-ross closed 9 years ago

ian-ross commented 9 years ago

If you have a C function defined as

bool fun(int, char *);

then creating the wrapper function for marshalling the bool return value will fail with an unsatisfied pattern match in C2HS.Gen.Wrapper because the makeArg function there only matches C function parameters with names.
