Yes, yes, yes :-) I have read all that a long time ago ...

Agreed.

Agreed, the supplementary groups I observe on Unix are relevant to me ... I know
that out of experience.

The difference is, that all supplementary groups show up in the /etc/group file on
my Unix box ...

However, as you know, the supplementary group to which I referred above do NOT show
up in my /etc/group file on Cygwin (they show up in SAM ... somewhere).

... and I do not care, as these groups are NOT relevant to me as a Cygwin-only user
of the Windows operating system (using passwd and group files).

Sorry, for having a different opinion on the matter.

Henri
