     *  If e.g. UNIX APIs are used, they'll have portability issues with
     *  very small and very large years.
     *
     *  Current approach:
     *
     *  - Stay within portable UNIX limits by using equivalent year mapping.
     *    Avoid year 1970 and 2038 as some conversions start to fail, at
     *    least on some platforms.  Avoiding 1970 means that there are
     *    currently DST discrepancies for 1970.
     *
     *  - Create a UTC and local time breakdowns from 't'.  Then create
     *    a time_t using gmtime() and localtime() and compute the time
     *    difference between the two.
     *
     *  Equivalent year mapping (E5 Section 15.9.1.8):
     *
     *    If the host environment provides functionality for determining
     *    daylight saving time, the implementation of ECMAScript is free
     *    to map the year in question to an equivalent year (same
     *    leap-year-ness and same starting week day for the year) for which
     *    the host environment provides daylight saving time information.
     *    The only restriction is that all equivalent years should produce
     *    the same result.
     *
     *  This approach is quite reasonable but not entirely correct, e.g.
     *  the specification also states (E5 Section 15.9.1.8):
     *
     *    The implementation of ECMAScript should not try to determine
     *    whether the exact time was subject to daylight saving time, but
     *    just whether daylight saving time would have been in effect if
     *    the _current daylight saving time algorithm_ had been used at the
     *    time.  This avoids complications such as taking into account the
     *    years that the locale observed daylight saving time year round.
     *
     *  Since we rely on the platform APIs for conversions between local
     *  time and UTC, we can't guarantee the above.  Rather, if the platform
     *  has historical DST rules they will be applied.  This seems to be the
     *  general preferred direction in Ecmascript standardization (or at least
     *  implementations) anyway, and even the equivalent year mapping should
     *  be disabled if the platform is known to handle DST properly for the
     *  full Ecmascript range.
     *
     *  The following has useful discussion and links:

             *  "/" followed by something in regexp mode.  See E5 Section 7.8.5.
             *
             *  RegExp parsing is a bit complex.  First, the regexp body is delimited
             *  by forward slashes, but the body may also contain forward slashes as
             *  part of an escape sequence or inside a character class (delimited by
             *  square brackets).  A mini state machine is used to implement these.
             *
             *  Further, an early (parse time) error must be thrown if the regexp
             *  would cause a run-time error when used in the expression new RegExp(...).
             *  Parsing here simply extracts the (candidate) regexp, and also accepts
             *  invalid regular expressions (which are delimited properly).  The caller
             *  (compiler) must perform final validation and regexp compilation.
             *
             *  RegExp first char may not be '/' (single line comment) or '*' (multi-
             *  line comment).  These have already been checked above, so there is no
             *  need below for special handling of the first regexp character as in
             *  the E5 productions.
             *
             *  About unicode escapes within regexp literals:
             *
             *      E5 Section 7.8.5 grammar does NOT accept \uHHHH escapes.
             *      However, Section 6 states that regexps accept the escapes,
             *      see paragraph starting with "In string literals...".
             *      The regexp grammar, which sees the decoded regexp literal
             *      (after lexical parsing) DOES have a \uHHHH unicode escape.
             *      So, for instance:
             *
             *          /\u1234/
             *
             *      should first be parsed by the lexical grammar as:
             *
             *          '\' 'u'      RegularExpressionBackslashSequence
             *          '1'          RegularExpressionNonTerminator
             *          '2'          RegularExpressionNonTerminator
             *          '3'          RegularExpressionNonTerminator
             *          '4'          RegularExpressionNonTerminator
             *
             *      and the escape itself is then parsed by the regexp engine.
             *      This is the current implementation.
             *
             *  Minor spec inconsistency:
             *
             *      E5 Section 7.8.5 RegularExpressionBackslashSequence is:
             *
             *         \ RegularExpressionNonTerminator
             *
             *      while Section A.1 RegularExpressionBackslashSequence is:
             *
             *         \ NonTerminator
             *
             *      The latter is not normative and a typo.
             *

     *    - E5 Section 15.3.4.5.2: for "bound" Function objects
     *
     *  The chain of bound functions is resolved in Section 15.3.4.5.2,
     *  with arguments "piling up" until the [[Construct]] internal
     *  method is called on the final, actual Function object.  Note
     *  that the "prototype" property is looked up *only* from the
     *  final object, *before* calling the constructor.
     *
     *  Currently we follow the bound function chain here to get the
     *  "prototype" property value from the final, non-bound function.
     *  However, we let duk_handle_call() handle the argument "piling"
     *  when the constructor is called.  The bound function chain is
     *  thus now processed twice.
     *
     *  When constructing new Array instances, an unnecessary object is
     *  created and discarded now: the standard [[Construct]] creates an
     *  object, and calls the Array constructor.  The Array constructor
     *  returns an Array instance, which is used as the result value for
     *  the "new" operation; the object created before the Array constructor
     *  call is discarded.
     *
     *  This would be easy to fix, e.g. by knowing that the Array constructor
     *  will always create a replacement object and skip creating the fallback
     *  object in that case.
     *
     *  Note: functions called via "new" need to know they are called as a
     *  constructor.  For instance, built-in constructors behave differently
     *  depending on how they are called.
