Wrong type for 2nd arg of getgroups under vax-dec-ultrix4.3 in fixed unistd.h

[John David Anglin]

According to the man page for getgroups, the type of the second argument
should be "int *".  The type in the fixed version of unistd.h is "short *".
I think this happens because the type of gid_t is short under
vax-dec-ultrix4.3.  This happens both with egcs-2.91.57 and gcc-2.8.1.
