I've attached a patch to "acinclude.m4" to make it do so; I don't have a
machine handy with UCD SNMP's headers installed in
"/usr/local/include/ucd-snmp", so could somebody who does (and who also
has the UCD SNMP library installed in "/usr/local/lib" apply this patch,
run "autogen.sh", and test the resulting configure script by running it
*without* any SNMP-related configure flags (i.e., don't tell it where to
look for the UCD SNMP library, just run "./configure" with no
arguments)?
