>Description:

rxvt compilation fails:

logging.c: In function 'rxvt_update_lastlog':
logging.c:383:21: error: storage size of 'llx' isn't known
     struct lastlogx llx;
                     ^

This is because :

/* Define location of utmpx */
/* #undef RXVT_UTMPX_FILE */

and so rxvt.h does #undef HAVE_UTMPX_H and so it is not included.

>How-To-Repeat:
Try to build rxvt on netbsd-current.

>Fix:
n/a
