math.h typo

[Stephen L Moshier]

I believe this constant in math.h is spelled wrong, with the result that
the compiled value is off by a bit in 128-bit quad precision.
 I get
   1.0/ln(2) = 1.44269504088896340735992468100189213742664595

	 * math/math.h (M_LOG2El): Correct the value.

*** math.h	2002/08/28 00:02:21	1.1
