Error compiling cloop module

[dafne]

Hi all!

I want to remaster Flonix, a Knoppix version, with 2.4.20 kernel and freeswan support, and I try to compile cloop-module-0.67-1. It doesnt compile, and says:

root@0[cloop]# make KERNEL_DIR=/usr/src/linux
cc -Wall -O2 -s -I. -fomit-frame-pointer -D__KERNEL__ -DMODULE -I/usr/src/linux/include -D__SMP__ compressed_loop.c -c -o compressed_loop.o
tcc: invalid option -- '-s'
make: *** [compressed_loop.o] Error 1

Could it be -s option means it needs any package I dont have, or whatever thing?

Thanks in advance.
