This is a very bad idea. sys/malloc.h is the malloc used in the kernel, 
and it does nothing for a BSD-like system WRT malloc()/free(); in fact 
all it is giving you is namespace pollution. MACOS and *BSD just need 
unistd.h to get malloc/free, and it is an error to include the 
deprecated malloc.h.

The above should look like

#ifndef MACOSXplatform
#include <malloc.h>

or (if unistd.h is not already there)

#ifdef MACOSXplatform
#include <unistd.h>
#include <malloc.h>

but I doubt that is neceassary.
