The reason for me to have such an old version is that I could not find a more recent version for this old Kindle Fire Gen 5 tablet.
Haven't been able to find the corresponding user manual.
Note: Why at this site have to hit spacebar twice in order to have a space inserted between words? Other quirkinesses in relation to other puntuation symbols like: :, , ( & ).

Gnuplot is an open source project. This means that anyone can download the source and adapt it for some local need. Apparently someone did that, years ago, to produce an executable for the Kindle. It would have been polite for them to follow community standards and honor the open source license by feeding those local adaptations back to the upstream project (that's us), but they didn't. So we don't know anything about this Kindle version and cannot answer your questions.
If you do track down the people who produced the Kindle executable, maybe you can get them to contribute the changes they made back to the gnuplot project. Even though the source code version it applied to is long out of date, it might nevertheless allow us to update it and add Kindle-like tablets as a supported platform.
Your interest in achieving Kindle support is welcome, but at this point you seem to have more information about it than we do so I think the ball is in your court.

This version makes use of the DOSbox emulation environment, and has been tested to ensure numerical accuracy. Enhancements to the mathematical capabilities of DOSbox (which will be made available soon as "gDosBox") were made to ensure the operational accuracy of GNUplot37.

So it's a copy of an MSDOS gnuplot executable running inside an emulator on top of Android? Hmm. That seems like a very round-about way to run something.
However...
I've already suggested elsewhere that a better approach is to use the emscripten translator to produce a javascript gnuplot executable that can be run inside a browser on Android or anywhere else for that matter. For an online javascript gnuplot 4.6 see http://gnuplot.respawned.com
I would welcome contribution of patches to the gnuplot build scripts so that producing a javascript executable via emscripten is a simple configuration option. Obviously you'd need to have the appropriate compilers installed.

if this is the "Kindle" version, than it might not have any modifications:

Anyhow if that's the case, then you might be able to upgrade from 3.7 to 4.6 by using the DJGPP binary https://sourceforge.net/projects/gnuplot/files/gnuplot/4.6.0/gp460dj2.zip
run inside that same emulator.
