Does Net-SNMP 5.4.2.1 build OK on your Cygwin setup with "./configure
--with-defaults --without-perl-modules" ?

Regarding your questions:
* The libtool warning is harmless as far as I know.
* The linker error on  _snmpNotifyFilterTable_vacm_view_subtree is reported
because the notification-log-mib is included (implicitly) but the
notification MIB has been excluded (explicitly).
* The linker error on _run_exec_command is reported because a MIB has been
included (implicitly?) that requires agent/mibgroup/utils_funcs.c but the
"utilities" MIB module has been excluded (explicitly).
* The linker error on vacm_standard_views is caused by excluding mibII,
which also excludes mibII/vacm_conf. vacm_standard_views is defined in
mibII/vacm_conf.c.
* The linker error on sigrelse() looks like a Cygwin issue. Are you perhaps
using an old Cygwin version ? Recent Cygwin versions should have sigrelse().
See e.g. http://www.cygwin.com/ml/cygwin/2005-04/msg00660.html and
http://www.mail-archive.com/[email protected]/msg03475.html.
