 PURPOSE
    Indicates to the library that an 'atexit()' routine is _not_ to be installed
 USAGE
    herr_t H5dont_atexit(void)
 RETURNS
    Returns SUCCEED/FAIL
 DESCRIPTION
        This routine indicates to the library that an 'atexit()' cleanip routine
    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.
