I’m taking a dip in the Clang waters,

```julia
┌ Warning: not wrapping CLCursor (CLMacroInstantiation) RLAPI
└ @ Clang ~/.julia/packages/Clang/CiPzM/src/wrap_c.jl:443
┌ Warning: not wrapping CLCursor (CLMacroInstantiation) RLAPI

...

```

Haven’t been able to track down any information as to what might be going on so hoping someone has seen this before and can explain.

Thanks.

edit: RLAPI is in fact the thing that it is complaining about, it’s defined as part of an if statement, so I just need special handling for it.

Those `CLMacroInstantiation` warnings can be safely ignored. 🙂
