Indeed.

I really really really do not like to see multiple definitions of types
in separate user-visible headers, *even* if they are protected from
multiple declarations.  Such practices are just asking for trouble --
things will eventually break and the complication is simply not necessary.

Either include <sys/types.h> within <sys/mman.h>, *or* leave well enough
alone and let application programmers RTFM and include <sys/types.h>
themselves just as the manual page instructs them to do.

(I would slightly prefer that <sys/mman.h> automatically include
<sys/types.h> since that is what Solaris (SunOS-5.6) does.)
