+Subject: [PATCH] sys/cdefs.h: add definition of __attribute_alloc_size__
+
+Commit cee0b058fa0b4501b289a2da365182d60314d746 ("add aligned_alloc
+required for latest gcc libstdc++") added the prototype of
+aligned_alloc() to <stdlib.h>. This prototype contains
+'__attribute_alloc_size__ ((2))', but this is not defined anywhere in
+uClibc-ng.
+
+This commit addresses that by adding the relevant definition in
+<sys/cdefs.h>, borrowed from glibc.
