    It's compiled into the kernel, and the value can typically be discovered
    in a header file somewhere under /usr/include. For example, on HP-UX
    10.20:

    imadev:~$ find /usr/include -print | xargs grep NGROUPS_MAX
    /usr/include/sys/getaccess.h:#include <limits.h> /* just for NGROUPS_MAX */
    /usr/include/sys/unistd.h:# define _SC_NGROUPS_MAX 3 /* NGROUPS_MAX: Max # of simultaneous
    /usr/include/limits.h:# define _POSIX_NGROUPS_MAX 0 /* The number of simultaneous
    /usr/include/limits.h:# define NGROUPS_MAX 20 /* Maximum number of simultaneous

    That's trickier, unless you're prepared to edit the source code and
    stick a system("/usr/bin/id"); in it. I can't think of any good way. :(
