| This function is missing on some platforms: | |
| AIX 5.1, mingw, MSVC 14. | |
| @item | |
| 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). | |
