Thanks! Please do not post to both the gcc-help and gcc mailing lists. A question like this is only appropriate for gcc-help. Actually, it's not really even appropriate for gcc-help, since the question is not about gcc. This is a question about the C language. I would try to answer your question, but unfortunately I don't understand it. Since this only has to do with C, not with gcc, I recommend comp.lang.c, which you can reach at, e.g.: http://groups.google.com/group/comp.lang.c/topics Ian
