Re: dev build problem

I also noticed that lt-octave-gui is trying to load .oct files from the locally installed octave:

 ./lt-octave-gui

Not sure if this is OK or not.

It builds with 43d0785ca28f tip, but when i star octave I get the message:

./run-octave

On buildbots this message is redirected to system logger.

this is with gcc version 11.2.1 20210728 (Red Hat 11.2.1-1) (GCC).

A similar problem with clang 12.0.1.
