IIRC objc/runtime.h is a private header used internally while compiling libobjc. It is not for users and so it is not installed.

Very odd; looking at the Makefile, you seem to be correct, but it's installed on FreeBSD anyway. Could someone who understands how the configure script works add a check for the existence of runtime.h?

Given Nicola's comment may I suggest you change libobjc2 instead and move the relevant definitions to a publicly visible header, probably <objc/objc-api.h>.

I think you will then be able to copy's already existing logic that tests for the presence of objc_msg_forward2 and check for the availability of objc_msg_forward3 and/or objc_proxy_lookup and don't have to include non-portable headers.
