I'd be happier with an obvious placeholder entry in NEWS that makes it
clear we need to go back and edit it before release.

@deftypefn needs the "category" argument.
To drop it, make it @deftypefun.

> -@comment unistd.h
>  @comment SVID
>  @deftypefn {System V Function} int getpgid (pid_t @var{pid})

This should now be:

@comment POSIX.1
@deftypefun int getpgid (pid_t @var{pid})

>     New programs should always use `setpgid' instead.

We should refer to it as the POSIX.1 interface, not the SysV interface.

Otherwise looks OK to me.


Thanks,
