Perhaps we could do something like the following:

union malloc_max_size
{
    int i;
    size_t s;
    double d;
    void *p;
};

union malloc_alignment
{
    char c;
    union malloc_max_size u;
};

#define MALLOC_ALIGNMENT	(offsetof(struct fooalign, u))
#define MALLOC_HEADER_SIZE	(sizeof(union malloc_max_size))
