Only warnings, so probably OK. The X11 code is ancient. One of these
days eximon should be rewritten to use a modern toolkit. Here is a
comment from OS/Makefile-Default:

# A modified version of the Athena TextPop module is supplied with Exim. The
# modification is to remove the "replace" part of the "search and replace"
# operation because it isn't wanted. TextPop is only one of a number of
# modules that make up the Text widget. Some antique link editors cannot handle
# the case of a replacement module for one of a set of modules. To allow
# the monitor to be linked in such cases, set the value of EXIMON_TEXTPOP
# to be empty. The search operations will then contain a useless "replace"
# option, which is untidy, but does no harm.                           


EXIMON_TEXTPOP=em_TextPop.o

Something needs including to get these macros. On my Linux box these
values are defined in

/usr/include/arpa/nameser_compat.h:

which is included by

/usr/include/arpa/nameser.h

which is included by Exim's "#include <arpa/nameser.h>".

I note that the actual definitions are of the form

#define T_CNAME              ns_t_cname


so it looks like a naming change. I will insert some conditionals
definitions to check for the ns_t_ formats and define the old ones
myself if they aren't already defined. Maybe that will solve this one.

These are a consequence of the lack of T_ macros, I think.
