Error after I add RTS_OSPF_EXT in filter

[Владислав Гришин]

I change filter from 

filter import_exclude_default {
    if ( source != RTS_BGP && net != 0.0.0.0/0 ) then {
        print "net accepted:", net;
        ospf_metric1 = 60;
        accept;
    }
    reject;
}

to

filter import_exclude_default {
    if ( source = RTS_OSPF_INT && net != 0.0.0.0/0 ) then {
        print "net accepted:", net;
        ospf_metric1 = 60;
        accept;
    }
    reject;
}

after 'configure soft' I see error

bird> configure soft
Reading configuration from /etc/bird.conf
/etc/bird.conf, line 167: RTS_OSPF_INT: variable expected.

Why I receive error?
