*Purpose:
*	Definitions of operator>>(long double) member function for istream

*Revision History:
*       09-26-91  KRS   Created.  Split off from istream.cxx for granularity.
*       12-30-92  KRS   Fix indirection problem with **endptr.
*       05-10-93  CFW   Re-enable function, use strtod since no _strtold.
*       06-14-95  CFW   Comment cleanup.
