problem with builbing sfs

Hi!

I am trying to build sfs-0.7.2 on suse linux 9.1 with compiler gcc v3.3.3.
While running the make file I get the error:

g++ -DHAVE_CONFIG_H -I. -I../../sfs-0.7.2/./crypt -I..

What is the problem? IS something wrong with the code?
I would really appreciate any help you could give me!

Thanks!
