Hmm, I'm afraid we have to grow our buffer size until 2 successive runs return 
the same value and that value is not -1.

But - do we want to fix it now, when we don't even know that else would be 
needed for Tru64 port? There's even no Tru64 paragraph in Makefile yet.

PS: I have no ambition to port git to Tru64 since that test machine is 
accessible via friend of my friend - so I have to IM him the code and he 
returns value :)
