The crt0.S file is attached. It contains some interrupt processing
code which doesn't properly belong there; maybe that code should be
removed. (I couldn't get inline assembly at file level in C code to
work. That's why the interrupt vectors are in this file.)

The runtime library was made with ar65, including object files from
'common' and 'runtime', along with one of the ctype.o files.

The standard C I/O routines don't work, of course, but those wouldn't
be useful for most NES applications anyhow. Sprintf() works properly
for preparing trace or debug messages to be displayed
