"It's not a bug -- it's a feature!"  ;-)

cl65 isn't as smart as gcc.  It doesn't look "over the hedge" to see what
else will be coming on the command line.  Instead, it obeys each object as
soon as it reaches that object.  cl65 compiles/assembles each source file
when it reaches that file's name on the line -- cl65 uses only the options
that it already has seen.

Those "-o" options are in the wrong place.  You must change the
command-rules in the makefiles.  Actually, it generally is a good idea to
put all option objects on the left side of command lines, and to put all
non-option objects on the right side of those lines (that advice is true
for most commands).

root/2> cl65 -I .. -c -o obj/out.o ../1/foo.c

root/2> cl65 -o --add-source -c foo.c
