See group(5):
In older implementations, a group cannot have more than 200 members. =
The
maximum line length of /etc/group is 1024 characters. Longer lines wi=
ll
be skipped. This limitation disappeared in FreeBSD 3.0.

The number 16 is from /usr/include/sys/syslimits.h. But my /etc/group
has 37 groups without problems.
In /usr/include/sys/_types.h and /usr/include/sys/stat.h gid_t is
defined as __uint32_t, a 32 bits unsigned integer.
