+// History:
+// 02/02/00 (Hand Optimized)
+// 04/04/00 Unwind support added
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 01/22/01 Corrected results for powl(1,inf), powl(1,nan), and
+//          powl(snan,0) to be 1 per C99, not nan.  Fixed many flag settings.
+// 02/06/01 Call __libm_error support if over/underflow when y=2.
+// 04/17/01 Support added for y close to 1 and x a non-special value.
+//          Shared software under/overflow detection for all paths
+// 02/07/02 Corrected sf3 setting to disable traps
+// 05/13/02 Improved performance of all paths
+// 02/10/03 Reordered header: .section, .global, .proc, .align;
+//          used data8 for long double table values
+// 04/17/03 Added missing mutex directive
+// 10/13/03 Corrected .endp names to match .proc names

+//   2. RSHF       = 1.1000..00 * 2^(63)
