wtmp logging.

We have Solaris as follows:

Machine hardware:   sun4u
OS version:         5.8
Processor type:     sparc
Hardware:           SUNW,Ultra-4

We are running wu-ftp version Version wu-2.6.1(1).

It seems wtmp_logging is not supported, but at various times including
logout we get a sys log message saying the file cannot be found.

ftpd.c has static int wtmp_logging hard coded to 1.  Before we change this
static, add a #define or generally hack around with the code, can any one
tell me what is the proper and safe way to indicate to the software not to
imnplement  wtm logging ?

Many thanks,

Andrew H.
