+Subject: [PATCH] Remove aligned_alloc support
+
+This causes build issues when targeting older versions of MacOS.  That could be
+fixed, but I don't have the ability to reproduce it at the moment, and it's a
+problem in the build system check code which is about to be entirely replaced
+anyway.
+
+Since, as far as I know, this does not actually add aligned allocation support
+to any real system (they all support one of the other methods), just remove it
+for now.
