I've been seeing the following for a week or so, and have deleted /usr/obj , re-cvsupped and run cd /usr/src && make cleandir && make cleandir make.conf is empty. Anyone got any ideas? ===> kerberos5/tools/make-roken (all) ===> kerberos5/tools/asn1_compile (all) cd /usr/src/kerberos5/tools/asn1_compile/../make-roken && make cc -O2 -fno-strict-aliasing -pipe -I/usr/src/kerberos5/tools/asn1_compile/../../../crypto/heimdal/lib/roken -I/usr/src/kerberos5/tools/asn1_compile/../../../crypto/heimdal/lib/asn1 -I. -DHAVE_CONFIG_H -I/usr/src/kerberos5/tools/asn1_comp ile/../../include -DINET6 -I/usr/obj/usr/src/tmp/legacy/usr/include -c /usr/src/kerberos5/tools/asn1_compile/../../../crypto/heimdal/lib/asn1/gen.c In file included from ./roken.h:61, from /usr/src/kerberos5/tools/asn1_compile/../../../crypto/heimdal/lib/asn1/gen_l ocl.h:51, from /usr/src/kerberos5/tools/asn1_compile/../../../crypto/heimdal/lib/asn1/gen.c :34: /usr/include/resolv.h:320: error: syntax error before "ns_tsig_key" *** Error code 1 Stop in /usr/src/kerberos5/tools/asn1_compile. *** Error code 1 Stop in /usr/src/kerberos5/tools. *** Error code 1 Stop in /usr/src. *** Error code 1
