I found that CC executes the following commands:

/lib/cpp -C -I/usr/include/CC test.c | cfront +L +ftest.c > test..c
cc -c test..c -lC -lm
mv test..o test.o
cc test.o -lC -lm -lC
nm a.out | munch > __ctdt.c
cc -c __ctdt.c
cc test.o -lC -lm __ctdt.o -lC

If the last line is
	cc test.o __ctdt.o -lC -lm -lC
we can get a correct executable a.out.

I am using the following command, because I don't dare to rewrite CC.

From sh:
	LIBRARY="-lC -lm" CC test.c

From csh:
	setenv LIBRARY "-lC -lm"
	CC test.c
