the best thing you could do is just
rm inc1.h
and then use -Iplan9. a more plan 9 like solution is to do one of
bind plan9/inc1.h inc1.h
bind -b plan9 .
but both of those are likely to confuse things in the future.
it turns out, accidentally i am sure, that you can also
chmod 0 inc1.h
and then cpp will not be able to read it and it will move
on to plan9/inc1.h.

this will have no effect.
it will stop passing -I. to cpp,
but cpp already searches . first no matter what its options are.
#include <foo.h> means find foo.h in the -I directories or else in a standard
directory.
#include "foo.h" means find foo.h in the current directory or else like <foo.h>
these rules are not specified by ansi, but it's what other unix compilers do
too.
