Compiling the shell utilities 1.7 on a 486 running Interactive Unix 2.2.1.

I get a warning compiling lib/getugroups.c, since getgrent is
undeclared.  Since this is not a POSIX function, I don't understand why
it is declare in the !_POSIX_VERSION part of the conditional.  Perhaps
it should just be declared unconditionally.

(As an aside, it also seems bizarre to me that there are #ifdef's for
`sun' and `ultrix' in the course of defining GETGROUPS_T.  Seems like
the hardware has absolutely nothing to do with whether gid_t is present.)

Also, in src/Makefile.in, I don't understand why `su' is not simply
included as part of `PROGS', rather than as a separate target that
always gets made.

I also had one serious problem, date always dumping core, but as that
turned out to be a problem in Autoconf, I'm reporting it separately.

Here are diffs.

        * src/Makefile.in (PROGS): include `su' here.
        (all): instead of separately here.

        * getugroups.c (getgrent) [_POSIX_VERSION]: declare this.
        (getgrent) [!_POSIX_VERSION]: don't declare it.
