How?  Consider that getgrent just enumerates /etc/group.  It doesn't
know for what purpose the calling application does it.  I don't think it
makes a lot of sense to call a OS function for each getgrent call to
fill out the gr_mem field on the fly.

Having said that, I don't intend to change this behaviour myself.
However, I'm certainly not averse to patches to Cygwin which add this
behaviour, as long as it's not getting too slow by this.
