Thanks.  Even though the exponent range is the same for both the
IEEE extended and quad ``long double'' formats and is probably
never going to change, I should probably add some macros for these
constants.  Perhaps after including <float.h>, it would simply be
#define LDBL_MAXEXP (LDBM_MAX * 2 - 1).
