second call to mmap() results in error

[Lavrentiev, Anton (NIH/NLM/NCBI) [C]]

> Forget mmap().

Why?  The response was:

> Adding the <unistd.h> fixes the problem in all its iterations -- the original mmap() 
> test works (without the call to ftruncate()), as well as the second one.

Note *the original*.
