SDCC is used only to compile the code for the FX2 for the USRP1.  That 
codebase is fairly static, and SDCC 3.0 doesn't really bring much to the 
table for that. The main change between SDCC 2.X and SDCC 3.X is that 
some intrinsic 8051-specific type-qualifiers changed syntax between 2.X 
and 3.X,
and the command names changed.

It's fairly straightforward to mechanically convert between 2.X and 3.X 
syntax--I've done that experimentally for FX2LIB, but I seriously don't have
the bandwidth at the moment to do this for the USRP1 code, and 
realistically, that's up to Ettus.
