+ * libgcc2.h (LIBGCC2_HAS_SF_MODE): New macro.
+ (LIBGCC2_HAS_DF_MODE, LIBGCC2_HAS_TF_MODE, LIBGCC2_HAS_XF_MODE): Make
+ the defaults false if BITS_PER_UNIT != 8.
+ (SFtype, SCtype, __fixsfdi, __floatdisf, __fixunssfSI, __fixunssfDI)
+ (__powisf2, __divsc3, __mulsc3): Guard with LIBGCC2_HAS_SF_MODE rather
+ than BITS_PER_UNIT != 8.
+ (L_fixdfdi, L_fixsfdi, L_fixtfdi, L_fixunsdfdi, L_fixunsdfsi)
+ (L_fixunssfdi, L_fixunssfsi, L_fixunstfdi, L_fixunsxfdi, L_fixunsxfsi)
+ (L_fixxfdi, L_floatdidf, L_floatdisf, L_floatditf, L_floatdixf): Remove
+ #undefs.
+ * libgcc2.c (__fixunssfDI, __fixsfdi, __floatdisf, __fixunssfSI)
+ (__powisf2, __divsc3, __mulsc3): Guard with LIBGCC2_HAS_SF_MODE.
