    should not be installed.  The major (only?) purpose for this is in
    situations where the library is dynamically linked into an application and
    is un-linked from the application before 'exit()' gets callled.  In those
    situations, a routine installed with 'atexit()' would jump to a routine
    which was no longer in memory, causing errors.
        In order to be effective, this routine _must_ be called before any other
    HDF function calls, and must be called each time the library is loaded/
    linked into the application. (the first time and after it's been un-loaded) 
 GLOBAL VARIABLES
 COMMENTS, BUGS, ASSUMPTIONS
    If this routine is used, certain memory buffers will not be de-allocated,
    although in theory a user could call HPend on their own...

 * Function:	HDstrtoll
 *
 * Purpose:	Converts the string S to an int64 value according to the
 *		given BASE, which must be between 2 and 36 inclusive, or be
 *		the special value zero.
 *
 *		The string must begin with an arbitrary amount of white space
 *		(as determined by isspace(3c)) followed by a single optional
 *              `+' or `-' sign.  If BASE is zero or 16 the string may then
 *		include a `0x' or `0X' prefix, and the number will be read in
 *		base 16; otherwise a zero BASE is taken as 10 (decimal)
 *		unless the next character is a `0', in which case it is taken
 *		as 8 (octal).
 *
 *		The remainder of the string is converted to an int64 in the
 *		obvious manner, stopping at the first character which is not
 *		a valid digit in the given base.  (In bases above 10, the
 *		letter `A' in either upper or lower case represetns 10, `B'
 *		represents 11, and so forth, with `Z' representing 35.)
 *
 *		If REST is not null, the address of the first invalid
 *		character in S is stored in *REST.  If there were no digits
 *		at all, the original value of S is stored in *REST.  Thus, if
 *		*S is not `\0' but **REST is `\0' on return the entire string
 *		was valid.
 *
 * Return:	Success:	The result.
 *
 *		Failure:	If the input string does not contain any
 *				digits then zero is returned and REST points
 *				to the original value of S.  If an overflow
 *				or underflow occurs then the maximum or
 *				minimum possible value is returned and the
 *				global `errno' is set to ERANGE.  If BASE is
 *				incorrect then zero is returned.
