Unsetting USER and LOGNAME causes a emacs core dump on a Sparc 4/20
running SunOS 4.1.  Looks like a NULL pointer bug.

    wolfgang@wsrcc ;-) unset USER
    wolfgang@wsrcc ;-) unset LOGNAME
    wolfgang@wsrcc ;-) emacs -nw -q
    Fatal error (11).Segmentation fault (core dumped)

    wolfgang@wsrcc ;-) cd /usr/local/emacs/src
