+C11 defines different max_align_t in stddef.h. It may either come from
+compiler (GCC, Clang) or provided by the system (DragonFly, musl libc).
+FreeBSD's Clang has neither due to bug 193594.
+
+So, keep the old behavior by renaming the type here to avoid building
+with -ansi (upstream nestegg) or -std=gnu89 (SUSE).

-GCC 5.0 defaults to -std=gnu11 which exposes max_align_t in its stddef.h.
-Clang also provides max_align_t but not on FreeBSD (see bug 193594).
