Very good read for anyone that wants to write this outdated language in 2016.

A valid implementation of malloc and free are:
static char mem[~0U];
static size_t nalloc;

void *malloc(size_t n)
{
void *p = mem+nalloc;
nalloc += n;
return p;
}

void free(void *p)
{
// no-op
}
The standard imposes to real semantic requirements on these functions.
malloc() is allowed to fail at any time.
