 The question is if Math.Pow() should be IEEE754 compatible. And is
 Unix  pow() expected to be IEEE754 compatible? If so, we can directly
 call unix pow(), and post bug reports to the gcc and MS people ;-)

+I can give you a more complete set of tests (the ones from Rotor). 
+However, right now, I do not think they will work because there is an 
+MCS problem with handeling decimals in multibounded arrays 
+(http://bugzilla.ximian.com/show_bug.cgi?id=42850), and that Rotor 
+test depends on that for the testing.
+I would suggest we try to do exactly as Microsoft does ;-).
+The 1^inf case looks really weird.
+What does the pow function in the Microsoft C runtime do? In Java?
