Follow-up Comment #1:

This suggested change has no noticable effect on compiling Octave with gcc
with a default configure run.

Was the suggestion in the report that Octave itself should be able to be built
with the -fvisibility=hidden gcc option, or was that meant to suggest that
third-party projects could compile with that option and still link properly
with the Octave libraries? The gcc wiki page seems to imply that the shared
library itself should be built with this option.

If that's correct, then that does not currently work for me.
Trying to build Octave with -fvisibility=hidden results in many link errors
when the octave-cli and octave-gui executables are built. Let me know if I'm
doing something wrong.

Attached patch is the change I am building with.
