Mon Jul 8 02:14:25 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> 

* math/math.h (_Mfloat_, _Mlong_double_): New macros, defined iff not
	already defined to float, long double.  Use those macros for _Mdouble_
	defns when including mathcalls.h.
	* math/Makefile [$(long-double-fcts) != yes] (CPPFLAGS): Append
	-D_Mlong_double_=double.
	Add more -lm functions to -lc because ldexp uses them.
	* math/Makefile (calls): Add s_finite, s_copysign, s_scalbn, s_modf.
	(routines): Remove s_modf, add s_frexpf, s_ldexpf; all but frexp and
	ldexp have both f and l code, and those have f though not l code.
