Details:

One use of Matlab is the autocoding function. Though it is a travesty, it is
commonly used in the industry I'm in. It produces surprisingly clear, but
horrifically buggy code.
Octave doesn't support autocoding of course, and that's not the problem here.
The problem here is that many scripts that are destined for autocoding but
also are used in regular Matlab have 'coder' references that direct the
autocoder to generate appropriate code. These coder references, like for
example

coder.varsize('some_var',[6,1],[0,1]);

are ignored when regular Matlab is running.

Unfortunately, Octave does not ignore these coder references and stops with an
error. This makes it difficult to produce mutually compatible code.
