/* This silly little file is here because gcc messes up badly with
* prototyping the getgroups() / setgroups() functions on SunOS.
* The problem is that on SunOS 4.x, there are two versions of each of
* these functions: the usual (non-SysV) version takes an array of ints:
* [gs]etgroups(int, int *)
* but the Sys V version takes an array of gid_t's:
* [gs]etgroups(int, gid_t *).
* Unfortunately, gcc insists on the latter. This isn't right for
* most compilations -- it won't work unless you link with the
* /usr/5lib version of libc.
* Hence this little file: it invokes [gs]etgroups declaring its
* argument as pointer to void, and _hope_ that this is the same
* size pointer as (gid_t *), (uid_t *), and (int *). If it is,
* all will work smoothly on any host, yet we avoid including
* the file <sys/unistd.h> wherein getgroups is inappropriately
* prototyped.
