I don't have Rob's book, but it sounds like he's using the fprintf()
from amiga.lib (not lc.lib) which understands AmigaDOS file handles.
Try linking with just amiga.lib, omitting whatever c-lib comes with
your compiler.

With Lattice version 5, something like this seems to work for me:
1> lc -v -b0 hello.c
1> blink lib:astartup.obj,hello.o to hello lib lib:amiga.lib

Of course, Open() returns a BPTR to a struct FileHandle, not a machine
pointer, so using it as or casting to a struct FileHandle is somewhat pointless 
without BADDR()'ing the returned value from Open() and only if you really 
want to goop around with FileHandle internals.

But what do I know.
