-/*  File   : stdtod.c (Modified version of str2dbl.c)
-    Author : Richard A. O'Keefe @ Quintus Computer Systems, Inc.
-    Updated: Tuesday August 2nd, 1988
-    Defines: double strtod (char *str, char**ptr)
-*/
-
-/*  This is an implementation of the strtod() function described in the 
-    System V manuals, with a different name to avoid linker problems.
-    All that str2dbl() does itself is check that the argument is well-formed
-    and is in range.  It leaves the work of conversion to atof(), which is
-    assumed to exist and deliver correct results (if they can be represented).
-
-    There are two reasons why this should be provided to the net:
-    (a) some UNIX systems do not yet have strtod(), or do not have it
-        available in the BSD "universe" (but they do have atof()).
-    (b) some of the UNIX systems that *do* have it get it wrong.
-	(some crash with large arguments, some assign the wrong *ptr value).
-    There is a reason why *we* are providing it: we need a correct version
-    of strtod(), and if we give this one away maybe someone will look for
-    mistakes in it and fix them for us (:-).

-/*  The following constants are machine-specific.  MD{MIN,MAX}EXPT are
-    integers and MD{MIN,MAX}FRAC are strings such that
-	0.${MDMAXFRAC}e${MDMAXEXPT} is the largest representable double,
-	0.${MDMINFRAC}e${MDMINEXPT} is the smallest representable +ve double
-    MD{MIN,MAX}FRAC must not have any trailing zeros.
-    The values here are for IEEE-754 64-bit floats.
-    It is not perfectly clear to me whether an IEEE infinity should be
-    returned for overflow, nor what a portable way of writing one is,
-    so HUGE is just 0.MAXFRAC*10**MAXEXPT (this seems still to be the
-    UNIX convention).
-
-    I do know about <values.h>, but the whole point of this file is that
-    we can't always trust that stuff to be there or to be correct.
