You could use pieces of RTEMS or all of it.  The code executive portion 
is intended to be very lean
99% C which depends upon inline assembly to touch HW and inline 
functions instead of macros.  It
includes a port of the FreeBSD TCP/IP stack.

We also have some test programs which seem to map from a code size 
perspective onto what I
would think of as baselines for user applications.  For example, one 
just starts and sysem and
shuts down (no printf) while the next does a printf so you can see the 
impact of doing that on
code size.  Another set show various networking configurations -- basic, 
with httpd, with ftpd.
