f8d830994a * 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.

c2e42adb64 * floatfns.c (Flog): Fix unescaped newline in string. 
* frame.c (Fnext_frame): Same.
	* textprop.c (Fprevious_single_property_change): Same.
	(syms_of_textprop): Same, for DEFVAR for
	`interval_balance_threshold'.

1cee204565 * 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.

56abb480f7 * 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.
