There is no reason why it should.  This "sys-protos.h" file is only
used internally by gcc, wherein the "auto-hosts.h" is also available.
"auto-hosts.h" is not installed, so <unistd.h> cannot depend upon it.
Also, the name GETGROUPS_T would pollute the user name space.  To get
around that, you would have to alias it to another name and get involved
in lots of ugly stuff better left alone.  From my vantage point,
what you have now should be just fine.
