−This function is missing on some platforms:

−AIX 5.1, mingw, MSVC 9, Interix 3.5, BeOS.

−On very old systems, this function operated on an array of @samp{int},
+
−even though that was a different size than an array of @samp{gid_t};
+
−you can use autoconf's AC_TYPE_GETGROUPS to set @code{GETGROUPS_T} to
+
−the appropriate size (since @code{getgroups} and @code{setgroups}
+
−share the same bug).
