Typically system file.h files are protected against multiple inclusion
with a '#ifndef FILE_H' '#define FILE_H' '#endif /* file.h */' wrapper.

If we care, the <unistd.h> file contents are mandated by
"POSIX Standard: 2.10 Symbolic constants" and other functions
may also be added to it...

A partial list appears to be here http://cplus.kompf.de/posixlist.html
after looking at a quick google search.
