  64  * WHAT'S UP WITH THIS FILE?
  65  *
  66  * This is where we define the mystical JNI_PUBLIC_API macro that works on all
  67  * platforms. If you're running with Visual C++, Symantec C, or Borland's
  68  * development environment on the PC, you're all set. Or if you're on the Mac
  69  * with Metrowerks, Symantec or MPW with SC you're ok too. For UNIX it shouldn't
  70  * matter.
  71
  72  * Changes by sailesh on 9/26
  73
  74  * There are two symbols used in the declaration of the JNI functions
  75  * and native code that uses the JNI:
  76  * JNICALL - specifies the calling convention
  77  * JNIEXPORT - specifies export status of the function
  78  *
  79  * The syntax to specify calling conventions is different in Win16 and
  80  * Win32 - the brains at Micro$oft at work here. JavaSoft in their
  81  * infinite wisdom cares for no platform other than Win32, and so they
  82  * just define these two symbols as:
  83
  84  #define JNIEXPORT __declspec(dllexport)
  85  #define JNICALL __stdcall
  86
  87  * We deal with this, in the way JRI defines the JRI_PUBLIC_API, by
  88  * defining a macro called JNI_PUBLIC_API. Any of our developers who
  89  * wish to use code for Win16 and Win32, _must_ use JNI_PUBLIC_API to
  90  * be able to export functions properly.
  91
  92  * Since we must also maintain compatibility with JavaSoft, we
  93  * continue to define the symbol JNIEXPORT. However, use of this
  94  * internally is deprecated, since it will cause a mess on Win16.
  95
  96  * We _do not_ need a new symbol called JNICALL. Instead we
  97  * redefine JNICALL in the same way JRI_CALLBACK was defined.
