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.
