Hi Stano,

Thank you for your report.

The ``config.h'' is not part of UCD-SNMP API headers, so, we can fix
that header as you suggested. But, to fix ``util_funcs.h'' is an issue.

As I could see (I tested original ucd-snmp-4.1.2 installation and the
latest ucd-snmp-4.2.7.1 package from net-snmp) normal ucd-snmp install
process does propagate two internal mibgroup's headers (struct.h and
util_funcs.h) under <prefix>/include/ucd-snmp directory. Thus, those
internal headers become the API headers.

Unfortunately, we have not the same headers under eCos <PREFIX>. The
eCos UCD-SNMP header files are all the UCD-SNMP's header files including
internal headers (not only API headers) and their subdirs. I think that
was KIS(s) principle as CDL command ``include_files'' does not let us to
change a structure of the package's headers under eCos <PREFIX>/include.

I think that we have to get all UCD-SNMP API headers in a right place,
i.e.  under <PREFIX>/include/ucd-snmp directory and I think we would use
CDL ``make'' command in snmpagent.cdl to copy absent headers there

 make -priority=1 {
  <PREFIX>/include/ucd-snmp/struct.h : <PACKAGE>/include/mibgroup/struct.h
  mkdir -p $(dir $@)
  cp -f $^ $(dir $@)
 }

and the same command for ``util_funcs.h'' header. Well, it's mine and
may be some one has either another view on your fix or yet another (own)
solution in CDL (I tested above).

Sergei
