Can fp maps have labels? If they can how can you make them? Related to this, does r.reclass only produce integer maps?

Yes; a reclass table maps integers to integers.

There are "FP reclass" functions in libgis, but these are only used by
r.recode. There are no functions to read/write a "struct FPReclass"
from/to a file, and no way to create an FP equivalent of a reclass
map.

Glynn:

Yes.

I have an old memory that d.legend used to show them, but now it seems it doesn't. I had been meaning to fire up GRASS 5.4 and look into that at some point.
