Here's a follow-up on the cause: 

    $ cat try.c 
    #include <sys/ptem.h>
    int main() {}
    $ cc -o try try.c
    In file included from try.c:1:
    /usr/include/sys/ptem.h:25: error: parse error before "mblk_t"
    /usr/include/sys/ptem.h:29: error: parse error before '}' token
    $ 

The mblk_t type is defined in sys/stream.h:

    $ cat try.c
    #include <sys/stream.h>
    #include <sys/ptem.h>
    int main() {}
    $ cc -o try try.c
    $

I don't know much of anything about termio and the only manual pages I
found referring to sys/stream.h were getq(9F) and friends.  I didn't
look too hard.  If you need additional information, let me know.  

By the way, I never received any confirmation of receipt of my
original message.  Is there anyone in there?
