Ok, that means the implementation is reduced to:
#if HAVE_DECL_AF_IB
rc = try_using_af_ib();
#else
rc = try_the_other_way();
#endif
Right? If so, I don't see why you need the AC_TRY_RUN -- if RDMACM is easily
detectable as to which way it is compiled (because it has, for example,
different fields), then AC_CHECK_DECLS should be enough, right?
I must be missing something...?
