Compilation error with net-snmp header files

OS: FreeBSD-4.10-RELEASE
    (with /usr/local/include/getopt.h header file added by some packages)
Net-SNMP: 5.2.1.2
Compiler: gcc-3.4.2

If I try to compile the following sample program:

#include <net-snmp/net-snmp-config.h>
#include <net-snmp/net-snmp-includes.h>
#include <net-snmp/agent/net-snmp-agent-includes.h>

#include <unistd.h>

int
main()
{
    exit(0);
}

with the following arguments:
g++34 `~/net-snmp/bin/net-snmp-config --cflags` bar.cc

it fails with the following errors:

pavlin@possum[483] g++34 `~/net-snmp/bin/net-snmp-config --cflags` bar.cc
In file included from bar.cc:5:
/usr/include/unistd.h:112: error: declaration of C function `int
getopt(int, char* const*, const char*)' conflicts with
/usr/local/include/getopt.h:115: error: previous declaration `int
getopt()' here
/home/possum/u0/pavlin/net-snmp/include/net-snmp/agent/agent_handler.h:238:
warning: inline function `void*
netsnmp_request_get_list_data(netsnmp_request_info*, const char*)'
used but never defined
Exit 1

The problem is that on FreeBSD getopt() may be declared in both
<unistd.h> and /usr/local/include/getopt.h, and we shouldn't include
both files. The latter is included by <net-snmp/utilities.h> if
HAVE_GETOPT_H is defined.

Also note the second (probably independent) error about
netsnmp_request_get_list_data() being used but never defined.

Both errors are with gcc-3.4 (and probably the gcc-4.x branch), but
are not with the gcc-2.95.4 compiler.
