3.7.1p1 appears to break pam session.

[Ralf Hack (new ext. 1216)]

Hi,
	I am running FreeBSD 4.7 and openssh 3.7.1p1. I have enabled 
PAM usage and indeed, I can use PAM for authentication purposes. 
Since configure does login_cap.h, the preprocessor is side stepping 
do_pam_session()
altogether in session.c:do_setusercontext().

	Here is my patch for session.c. My understanding about 
portability issues is rather limited. I would very much appreciate if 
you guys could check this and verify that I am not introducing more 
problems with this. So far this works for me.
