Sorry, this was not quite correct. The *.o files are only produced 
when they are not up to date. But the error messge remains.

After! It happened after I added a VPATH statement. Here's my 
makefile:

TARGET = rs.exe
CC = gpp
VPATH=objs
OBJECTS = main.o cstring.o config.o data.o

$(TARGET) : $(OBJECTS)
	$(CC) $(OBJECTS) $(LDFLAGS) -o $(TARGET)

%.o : %.cpp
	$(CC) $< $(WARNINGS) $(CXXFLAGS) -c -o $(VPATH)\$@

Hope I missed something. Thank you,

Manni
