 These links might shed some more light to the optimal
 placement of the idtype_t definition.
 
 http://www.unix.com/man-page/OpenSolaris/2/getacct/
 
 http://www.unix.com/man-page/OpenSolaris/2/sigsend/
 
 Both of these manual pages apply to Solaris-11. The same
 features are apparently also in HP-UX, but they are not
 SUS/POSIX - at least not yet.
 Esp. the sigsend() style functionality as a generalized
 kill() seems to me like a potential candidate to make it
 also to SUS/POSIX. Such functionality would be a natural
 companion to wait*() with generalized idtype_t and id_t.
 
 And in any case it seems likely that id_t and idtype_t
 will be used together almost anywhere where one is
 needed. Neither of them makes a whole lot sense
 without the other. So, keeping them together in the
 header files may be beneficial.
 
 Just my 0,02 EUR worth.
