* floatfns.c (Flogb): Always implement this by calling Flog, even
...
on non-USG systems, which supposedly have a logb function.
(Fround): Always implement this by calling floor, even on systems
that have rint.
* floatfns.c (IN_FLOAT): Make this work properly when SIGTYPE is void.

* floatfns.c (Flog): Don't forget to declare the BASE argument a
...
Lisp_Object.
* floatfns.c (Fexpt): Don't return the value of the XSET function
call; that's not guaranteed to be the value assigned.

* floatfns.c (Fexpm1, Flog1p): Function removed; it's not widely
...
available, and hardly vital.
(syms_of_floatfns): Adjusted appropriately.
* floatfns.c (Flog): Accept optional second arg, being the base
for the logarithm.
[USG] (Flogb): Define this in terms of Flog.
