Since WTMPX_FILE is a preprocesser #define it is not necessary to check
for it in configure in - we can do this directly in the source code.

This should work for FreeBSD and Linux - how do one get the pathname of
the wtmp and the utmp files on HPUX ?

#ifndef WTMP_FILENAME
#    ifdef WTMP_FILE
#        define WTMP_FILENAME WTMP_FILE
#    elif defined _PATH_WTMP /* FreeBSD */
#        define WTMP_FILENAME _PATH_WTMP
#    else
#        define WTMP_FILENAME "/etc/wtmp"
#    endif
#endif
