Note: bash in POSIX mode is not 100% POSIX guaranteed. It is really close.
The extensions are innate to bash. You do nothing special to make them switch on. You have to be aware of what ways turn them on, turn them off.
So you cannot view them. You may not know this, but you can add your own code and make it part of bash as well. This is not recommended because every upgrade/bugfix means you have to add your change back in.
on the first line of the script invokes native bash. NOT POSIX.
on the first line of the script invokes bash in POSIX mode. If /bin/sh is a symlink that points to bash

Thanks to all you guys about posix compliance I have learnt an enormous amount over the last few days.

shells
shells(4) File Formats shells(4)NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
/bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh,
/usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.
Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
