Thanks for this patch.

This is fixing autobuilder failures, so a reference to at least one
would have been good:

Since gnuplot uses git, we need that patch to be git-formatted:

    https://buildroot.org/downloads/manual/manual.html#_format_and_licensing_of_the_package_patches

(Yes I know the existing patch does not conform to that requirement, but
that is a old patch, from before we started enforcing any coding style.)

Also, did you send that patch upstream? If so, it would be super nice
that you include the URL to the bug-report, or mailing post, so that we
eventually bump gnuplot, we can get rid of that patch.

Care to rework and respin, please?

Regards,
Yann E. MORIN.
