io/fcntl.h already has, even in the context of your diff:

>  /* For XPG all symbols from <sys/stat.h> should also be available.  */
>  #ifdef __USE_XOPEN
>  # include <sys/stat.h>

That covers off_t and mode_t.  Can you verify that pid_t is really missing
on Linux configurations?  If it is missing only in Hurd configurations, we
should figure out how the difference arises before changing anything.


Thanks,
