No, you're probably right on target.  Functions like printf(), in any 
form, usually pull in a lot of other code.  It may be lazy programming 
on the part of the writer of the uIP stack, or, that that level of 
complexity is needed and that the target processor you've chosen is not 
capable of supporting the code.

"Champagne tastes on a beer budget"?  You might consider doing what I 
did.  I needed a lot of codespace to write a DOS layer for MMC, plus 
another goal was to put 11 programs into one processor (old product was 
64K EPROM on 8051).  The problem was that I needed 16K just to hold 
data, I have to track external events and give instant status reports 
when queried.  The solution was to use an LPC2138 to hold the very large 
code store, then use an LCP2106 to store the data in RAM.
