I wonder if it is not better to remove GRASS library dspf together with r3.mkdspf, which is the only tool depending on it, and r3.showdspf (not compiled since ages). See also #3867.

I'm not familiar with these parts of GRASS at all, but they seem to be unused and definitely unmaintained.
@neteler What do you say?

As the output of r3.mkdspf (manual) is a .dspf display file representing isosurfaces of a 3D raster (voxel) dataset, it can (only?) be used with the r3.showdspf visualization module (G54 (!) manual).

We already wanted to Decide the destiny of r3.mkdspf and r3.showdspf modules in GRASS 7... That tickets was opened 13 years ago and last modified 7 years ago. So, let's get finally rid of it.

Thanks! I wasn’t aware of that ticket. I’ll prepare a retirement PR.
