BSD license compatible hash algorithm?

The hash algorithm itself as implemented in hash.h is pretty much a 
text-book hash algorithm (D.J.Bernstein's):

#ifndef HASHINIT
#define HASHINIT        5381
#define HASHSTEP(x,c)   (((x << 5) + x) + (c))
#endif

/*
  * Return a 32-bit hash of the given buffer.  The init
  * value should be 0, or the previous hash value to extend
  * the previous hash.
  */
static __inline uint32_t
hash32_buf(const void *buf, size_t len, uint32_t hash)
{
         const unsigned char *p = buf;

         while (len--)
                 hash = HASHSTEP(hash, *p++);

         return hash;
}

It apparently has some weaknesses if used on binary (non-text) data but 
I don't see why it wouldn't work on Windows.
