[Bug 36481] CFNetworkCopySystemProxySettings and kCFNetworkProxiesProxyAutoConfigURLString are unavailable

--- Comment #1 from Ken Thomases  ---
How exactly are you building Wine?  In particular, the errors you quoted
suggest that the headers do in fact declare those identifiers but have marked
them as unavailable using attributes.  That suggests you are building with an
SDK more recent than 10.5 but setting the deployment target to 10.5.

The typical solution would be to wrap the relevant code with:

#if defined(MAC_OS_X_VERSION_10_5) && MAC_OS_X_VERSION_MAX_ALLOWED >=
MAC_OS_X_VERSION_10_5
...
#endif

I'm not sure if that will help, depending on how you're building.
