I don't think it's relevant. I also don't think that float.el is what people would use if they want Emacs to support floating point (it's probably more efficient to use a libc or libm implementation instead). Finally, I seriously doubt that Emacs as it currently stands can be built without floating point support. Looks like we need a reality check here. If someone wants to get a "float-free Emacs" working, fetching float.el from the obsolete subdirectory (or even from a tarball of an old Emacs version) will be the least of the guy's worries. Stefan
