I agree, I don't see CGContextCopyPath described in the 10.5 SDK headers.
I've encountered this in other situations. Apple documentation's notion of when
a symbol became available seems to refer to the libraries, not necessarily the
headers. Sometimes they introduce a function in an OS version but don't
publicly announce it (or add it to the SDK) until later. So you could either
use the 10.6 SDK, or else add the needed definitions from the 10.6 SDK to your
project headers somewhere (when using an earlier SDK).
