Sandor,

Thanks for correcting me....

You're right, I think the reason has something to do with standards

It doesn't look like a good idea to change this.....

If you change it in that include file, the value will only be changed
in applications that you subsequently compile that use that file. It
won't do you any good for applications that are already compiled; also,
there probably is a real reason why that number is 64; I doubt it is
arbitrary.

In short, changing the value of NGROUPS_MAX in /usr/include/grp.h will
not have the desired effect, and will probably break things that you
may compile in the future.
