Should we really care to keep our code suboptimal just to make it 
readily reusable by other projects?  That seems a bit backward to me.

We might simply add a comment telling people what git-compat-util.h is 
actually for, namely memcpy(), ntohl() and htonl().  That should be 
trivial for them to use the appropriate substitute.
