Yes, it is a bit sad.  Somewhere I have some half-baked patches that allow you 
to stub out the majority of the gconv and wchar code at configure time; I did 
this for an internal project where the resulting binaries had to fit into ROM.

The other thing I looked at was dropping the stdio implementation from newlib 
(which is far less featureful but also a whole lot smaller) into libc.  I 
think I got that to mostly work and again I can probably dig out some patches 
if anyone is interested.
