// V8 Version Macro
// ----------------
// v8 does not (until now) provide a version macro - which is still discussed and may come soon.
// Until then, we set a default version which can be overridden via command line using V8_VERSION:
// swig -javascript -v8 -DV8_VERSION=0x031110
//
// v8 added version macros V8_MAJOR_VERSION, V8_MINOR_VERSION, V8_BUILD_NUMBER
// and V8_PATCH_LEVEL in version 4.3.0. SWIG generated code uses these if
// they are defined - to support earlier versions you can specify the V8 version
// in use via the command line when you run SWIG:
//
// swig -c++ -javascript -v8 -DV8_VERSION=0x032530 example.i
//
// Or code in the interface file using SWIG_V8_VERSION:
//
// %begin %{#define SWIG_V8_VERSION 0x031110%}
//
// This is specified as a hex constant, but the constant is read as pairs of
// decimal digits, so for V8 3.25.30 use constant 0x032530. This scheme can't
// represent components > 99, but this constant is only useful for V8 < 4.3.0,
// and no V8 versions from that era had a component > 99.
