Portability problems not fixed by Gnulib:

  * This function is unsafe to call between fork and exec if the parent process is multi-threaded.  Instead, use getgroups or getgrouplist (or use the gnulib module mgetgroups) before forking, and setgroups in the child.

  * This function is missing on some platforms: mingw, MSVC 9, Interix 3.5, BeOS.
