Description
Section 6.6 of the LFS book sets up /etc/group so that tty is gid 4 and tape is gid 5. The GNU Screen source code assumes tty will have gid 5. PTYs created by screen sessions will thus end up with a group of "tape" instead of "tty"--which will manifest itself in subtle ways (like the mesg command from util-linux refusing the change permissions).
The best fix is obviously to update screen's logic to use getpwnam, but short of that this issue can be fixed by adding "--with-pty-group=4" to screen's configure step.

What a curious package. The code hasn't bee updated since 2006 and the gid info dates back to 1987. A proper fix to the code would be to actually ask the system what gid was associated with tty, but that capability was probably added well after this code was written.
Used the suggested --with-pty-group=4.
Fixed at revision 9903.
