Sounds like you've got a library/include file mismatch. There are two
"families" of libraries for the gcc: the original library by John Dunning,
that came with gcc 1.23, and derivatives (including, I think, the one that
comes with g++); and the gcc 1.37 library that Jwahar Bammi and I put together,
and derivatives (including one by Edgar Roeder, and the MiNT library). The
former has _printf_guts and stdout; the latter has _doprnt and _iob[].
My suspicion is that you're using header files for the first library with
a gnu.olb that's set up for the second library.
