You should probably use mkoctfile-4.0.3 here, or better yet just call
mkoctfile from within Octave, there is no need to run a shell.

I don't know and I can't reproduce this. If you can provide the full
source to your project, maybe someone can help more than stabbing in the
dark.

A stab in the dark: it may be something that came before the macro, like
a missing semicolon or end brace.
