        * libc/include/machine/ieeefp.h: Change to only define
        floating point defines (e.g one of __IEEE_BIG_ENDIAN or
        __IEEE_LITTLE_ENDIAN must be defined for each platform).
        * libc/include/sys/config.h: Include <machine/ieeefp.h> and
        remove redundant floating point definitions.

+   __IEEE_BIG_ENDIAN

+        Defined if the float format is big endian.  This is mutually exclusive
+        with __IEEE_LITTLE_ENDIAN.

+   __IEEE_LITTLE_ENDIAN
+ 
+        Defined if the float format is little endian.  This is mutually exclusive
+        with __IEEE_BIG_ENDIAN.
+
+   Note that one of __IEEE_BIG_ENDIAN or __IEEE_LITTLE_ENDIAN must be specified for a
+   platform or error will occur.
+
+   __IEEE_BYTES_LITTLE_ENDIAN
+
+        This flag is used in conjunction with __IEEE_BIG_ENDIAN to describe a situation 
+	whereby multiple words of an IEEE floating point are in big endian order, but the
+	words themselves are little endian with respect to the bytes.
+
+   _DOUBLE_IS_32_BITS 
+
+        This is used on platforms that support double by using the 32-bit IEEE
+        float type.
+
+   _FLOAT_ARG
+
+        This represents what type a float arg is passed as.  It is used when the type is
+        not promoted to double.
