Re:

+# if O_SEARCH != O_RDONLY || (defined _WIN32 && !defined __CYGWIN__)
+        /* There is no point to forking if O_SEARCH conforms to POSIX,
+           or on native MS-Windows which lacks 'fork'.  */
+        bool try_fork = false;
+# else
+        bool try_fork = errno == EACCES || errno == ESTALE;
+# endif
+        if (!try_fork)

iOS also lacks fork/exec, posix_spawn, etc. Apple wants devs to use
NSTask to create processes. (iirc).
