Automatically removed temporary object files

[Frank]

I've a problem that temporary object files are deleted, which I do not
want.

Example:

Makefile:

OBJECTS = A.o B.o C.o

%.exe: %.c $(OBJECTS)
    gcc $< $(OBJECTS) -o $@

%.o: %.c
    gcc -c $< -o $@

Calling:

$ make test.exe

results in:

gcc -c A.c -o A.o
gcc -c B.c -o B.o
gcc -c C.c -o C.o
gcc test.c A.o B.o C.o -o test.exe
rm A.o B.o C.o

Please, watch the last line: There is an 'rm' which I did not write in
the makefile.
How can I disable that? It does not make sense to compiler A, B, and C
over and over again if test.c changes.

Best Regards

Frank.
