[Octave-bug-tracker] [bug #59375] [Doc pane] Function index largely dysfunctional

[Markus Mützel]

Follow-up Comment #22, bug #59375 (project octave):

I can confirm that without the patch, the function index doesn't work for MXE
Octave build for Windows. With the patch it works.

During compilation the compiler emits the following warnings for the changed
file:

Those are probably unrelated. I'm not sure if they are important.
