+  -V, --version           display version information and exit

+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files

+/* Decimal Number arithmetic module				      */
+/* ------------------------------------------------------------------ */
+/* This module comprises the routines for General Decimal Arithmetic  */
+/* as defined in the specification which may be found on the	      */
+/* http://www2.hursley.ibm.com/decimal web pages.  It implements both */
+/* the full ('extended') arithmetic and the simpler ('subset')	      */
+/* arithmetic.							      */
+/*								      */
+/* Usage notes:							      */
+/*								      */
+/* 1. This code is ANSI C89 except:				      */
+/*								      */
+/*       If DECDPUN>4 or DECUSE64=1, the C99 64-bit int64_t and	      */
+/*	 uint64_t types may be used.  To avoid these, set DECUSE64=0  */
+/*	 and DECDPUN<=4 (see documentation).			      */
+/*								      */
+/* 2. The decNumber format which this library uses is optimized for   */
+/*    efficient processing of relatively short numbers; in particular */
+/*    it allows the use of fixed sized structures and minimizes copy  */
+/*    and move operations.  It does, however, support arbitrary	      */
+/*    precision (up to 999,999,999 digits) and arbitrary exponent     */
+/*    range (Emax in the range 0 through 999,999,999 and Emin in the  */
+/*    range -999,999,999 through 0).  Mathematical functions (for     */
+/*    example decNumberExp) as identified below are restricted more   */
+/*    tightly: digits, emax, and -emin in the context must be <=      */
+/*    DEC_MAX_MATH (999999), and their operand(s) must be within      */
+/*    these bounds.						      */
+/*								      */
+/* 3. Logical functions are further restricted; their operands must   */
+/*    be finite, positive, have an exponent of zero, and all digits   */
+/*    must be either 0 or 1.  The result will only contain digits     */
+/*    which are 0 or 1 (and will have exponent=0 and a sign of 0).    */
+/*								      */
+/* 4. Operands to operator functions are never modified unless they   */
+/*    are also specified to be the result number (which is always     */
+/*    permitted).  Other than that case, operands must not overlap.   */
+/*								      */
+/* 5. Error handling: the type of the error is ORed into the status   */
+/*    flags in the current context (decContext structure).  The	      */
+/*    SIGFPE signal is then raised if the corresponding trap-enabler  */
+/*    flag in the decContext is set (is 1).			      */
+/*								      */
+/*    It is the responsibility of the caller to clear the status      */
+/*    flags as required.					      */
+/*								      */
+/*    The result of any routine which returns a number will always    */
+/*    be a valid number (which may be a special value, such as an     */
+/*    Infinity or NaN).						      */
+/*								      */
+/* 6. The decNumber format is not an exchangeable concrete	      */
+/*    representation as it comprises fields which may be machine-     */
+/*    dependent (packed or unpacked, or special length, for example). */
+/*    Canonical conversions to and from strings are provided; other   */
+/*    conversions are available in separate modules.		      */
+/*								      */
+/* 7. Normally, input operands are assumed to be valid.	 Set DECCHECK */
+/*    to 1 for extended operand checking (including NULL operands).   */
+/*    Results are undefined if a badly-formed structure (or a NULL    */
+/*    pointer to a structure) is provided, though with DECCHECK	      */
+/*    enabled the operator routines are protected against exceptions. */
+/*    (Except if the result pointer is NULL, which is unrecoverable.) */
+/*								      */
+/*    However, the routines will never cause exceptions if they are   */
+/*    given well-formed operands, even if the value of the operands   */
+/*    is inappropriate for the operation and DECCHECK is not set.     */
+/*    (Except for SIGFPE, as and where documented.)		      */
+/*								      */
+/* 8. Subset arithmetic is available only if DECSUBSET is set to 1.   */
+/* ------------------------------------------------------------------ */
+/* Implementation notes for maintenance of this module:		      */
+/*								      */
+/* 1. Storage leak protection:	Routines which use malloc are not     */
+/*    permitted to use return for fastpath or error exits (i.e.,      */
+/*    they follow strict structured programming conventions).	      */
+/*    Instead they have a do{}while(0); construct surrounding the     */
+/*    code which is protected -- break may be used to exit this.      */
+/*    Other routines can safely use the return statement inline.      */
+/*								      */
+/*    Storage leak accounting can be enabled using DECALLOC.	      */
+/*								      */
+/* 2. All loops use the for(;;) construct.  Any do construct does     */
+/*    not loop; it is for allocation protection as just described.    */
+/*								      */
+/* 3. Setting status in the context must always be the very last      */
+/*    action in a routine, as non-0 status may raise a trap and hence */
+/*    the call to set status may not return (if the handler uses long */
+/*    jump).  Therefore all cleanup must be done first.	 In general,  */
+/*    to achieve this status is accumulated and is only applied just  */
+/*    before return by calling decContextSetStatus (via decStatus).   */
+/*								      */
+/*    Routines which allocate storage cannot, in general, use the     */
+/*    'top level' routines which could cause a non-returning	      */
+/*    transfer of control.  The decXxxxOp routines are safe (do not   */
+/*    call decStatus even if traps are set in the context) and should */
+/*    be used instead (they are also a little faster).		      */
+/*								      */
+/* 4. Exponent checking is minimized by allowing the exponent to      */
+/*    grow outside its limits during calculations, provided that      */
+/*    the decFinalize function is called later.	 Multiplication and   */
+/*    division, and intermediate calculations in exponentiation,      */
+/*    require more careful checks because of the risk of 31-bit	      */
+/*    overflow (the most negative valid exponent is -1999999997, for  */
+/*    a 999999999-digit number with adjusted exponent of -999999999). */
+/*								      */
+/* 5. Rounding is deferred until finalization of results, with any    */
+/*    'off to the right' data being represented as a single digit     */
+/*    residue (in the range -1 through 9).  This avoids any double-   */
+/*    rounding when more than one shortening takes place (for	      */
+/*    example, when a result is subnormal).			      */
+/*								      */
+/* 6. The digits count is allowed to rise to a multiple of DECDPUN    */
+/*    during many operations, so whole Units are handled and exact    */
+/*    accounting of digits is not needed.  The correct digits value   */
+/*    is found by decGetDigits, which accounts for leading zeros.     */
+/*    This must be called before any rounding if the number of digits */
+/*    is not known exactly.					      */
+/*								      */
+/* 7. The multiply-by-reciprocal 'trick' is used for partitioning     */
+/*    numbers up to four digits, using appropriate constants.  This   */
+/*    is not useful for longer numbers because overflow of 32 bits    */
+/*    would lead to 4 multiplies, which is almost as expensive as     */
+/*    a divide (unless a floating-point or 64-bit multiply is	      */
+/*    assumed to be available).					      */
+/*								      */
+/* 8. Unusual abbreviations that may be used in the commentary:	      */
+/*	lhs -- left hand side (operand, of an operation)	      */
+/*	lsd -- least significant digit (of coefficient)		      */
+/*	lsu -- least significant Unit (of coefficient)		      */
+/*	msd -- most significant digit (of coefficient)		      */
+/*	msi -- most significant item (in an array)		      */
+/*	msu -- most significant Unit (of coefficient)		      */
+/*	rhs -- right hand side (operand, of an operation)	      */
+/*	+ve -- positive						      */
+/*	-ve -- negative						      */
+/*	**  -- raise to the power				      */
