+	* config.make.in: Add have-mfma4 entry.
+	* configure.in: Substitute libc_cv_cc_fma4.
+	* math/Makefile (dbl-only-routines): Add sincostab.
+	* sysdeps/ieee754/dbl-64/dosincos.c: Don't include sincos.tbl.
+	Use __sincostab not sincos.
+	* sysdeps/ieee754/dbl-64/e_asin.c: Don't define aliases when function
+	name is a macro.
+	* sysdeps/ieee754/dbl-64/e_exp.c: Likewise.

+	using __copysign.
+	* sysdeps/ieee754/dbl-64/mpa.c: Don't export __acr.  Don't define
+	__cr and __cpymn.  Define __cpy unless NO___CPY is defined.  Define
+	norm, denorm, and __mp_dbl unless NO___MP_DBL is defined.
+	* sysdeps/ieee754/dbl-64/mpa.h: Don't declare __acr, __cr, __cpymn,
+	and __inv.
