* 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.
