__attribute_alloc_size is currently defined only in the internal header 
include/sys/cdefs.h (with a definition that is neither conditioned on 
appropriate GCC versions support, nor namespace-clean), not the installed 
misc/sys/cdefs.h, so can't be used in installed headers without a separate 
patch to move it to the installed header and make it properly conditional 
and namespace-clean for that header.
