/*******************************************************************************
 * WHAT'S UP WITH THIS FILE?
 * 
 * This is where we define the mystical JNI_PUBLIC_API macro that works on all
 * platforms. If you're running with Visual C++, Symantec C, or Borland's 
 * development environment on the PC, you're all set. Or if you're on the Mac
 * with Metrowerks, Symantec or MPW with SC you're ok too. For UNIX it shouldn't
 * matter.

 * Changes by sailesh on 9/26 

 * There are two symbols used in the declaration of the JNI functions
 * and native code that uses the JNI:
 * JNICALL - specifies the calling convention 
 * JNIEXPORT - specifies export status of the function 
 * 
 * The syntax to specify calling conventions is different in Win16 and
 * Win32 - the brains at Micro$oft at work here. JavaSoft in their
 * infinite wisdom cares for no platform other than Win32, and so they
 * just define these two symbols as:

 #define JNIEXPORT __declspec(dllexport)
 #define JNICALL __stdcall

 * We deal with this, in the way JRI defines the JRI_PUBLIC_API, by
 * defining a macro called JNI_PUBLIC_API. Any of our developers who
 * wish to use code for Win16 and Win32, _must_ use JNI_PUBLIC_API to
 * be able to export functions properly.

 * Since we must also maintain compatibility with JavaSoft, we
 * continue to define the symbol JNIEXPORT. However, use of this
 * internally is deprecated, since it will cause a mess on Win16.

 * We _do not_ need a new symbol called JNICALL. Instead we
 * redefine JNICALL in the same way JRI_CALLBACK was defined.
