You mean what HP compile to create /usr/bin/sh and /sbin/sh on HP-UX systems?

Thats not open source software and you can't view it at all.

What are you trying to do?

I think Duncan hit the nail on the head. I searched google pretty extensively and came up blank, most likely because it's not open source.

As mentioned, this isn't OpenSource.
However, if you are interested in implementation details of shells greatly compliant to POSIX whose source is open there are plenty to choose.
For instance, Bash has a so called Posix Mode which can be enabled by commandline switch or environment variable.
You can download Bash sources from here
http://www.gnu.org/software/bash/
But there are also other shells available in source, like zsh, or pksh (a public domain Korn shell), and many more.

If you're stricly looking for a POSIX shell, the one included FreeBSD and possibly other BSDs is almost POSIX compliant, and from the man page: "it is not a Korn shell clone like pdksh". You could take a look at this one as well.
