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 configure.ac'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.
