I fetch head revision from CVS, compile and install, but neither my 
model nor headbugs don't compile. The error is same.

It won't works. First, one must modify 
$SWARMHOME/etc/swarm/Makefile.rules to this:
.SUFFIXES: .m .mm .xm

.m.o:
	$(OBJC) -c $(OBJCFLAGS) $(CPPFLAGS) $(DLLCPPFLAGS) $(EXTRACPPFLAGS) 
$(SWARMINCLUDES) $(GNUSTEPLIBINCLUDES) $<
.mm.o:  
	$(OBJC) -c $(OBJCFLAGS) $(CPPFLAGS) $(DLLCPPFLAGS) $(EXTRACPPFLAGS) 
$(SWARMINCLUDES) $(GNUSTEPLIBINCLUDES) $<
