Suggestions?

I am not sure if what I am asking is practical or not. I am writing a
STREAMS stack for a protocol over a serial connection. Tha catch is
that it is an embedded application and I need the object (streams.o) to
be as small as I can get it. The whole file system is on flash. 

How can I best reduce the size of the file. I am not using clone or
multi or loopback (maybe on loopback). I am doing straight put() &
putq() up and down. 

What modules is it posssible to leave out?

Thanks,
Bill!
