Hello, please review :

Bug :


change :


mostly I added  JNIEXPORT / JNICALL at some places  where  the win32bit build 
missed it .

A difference is  
Where I removed   a few  declarations  (one  decl   with one without  JNIEXPORT 
/ JNICALL – looked a bit strange ) .

Best regards , Matthias

Subject: Re: missing JNIEXPORT / JNICALL at some places in function 

That's most likely a result of the new JNIEXPORT I added as part of the mapfile 

I tried to match header file and C file, but I can certainly have missed cases. 
If I didn't get any warnings, it was hard to know what I missed.

Please do submit your patch.

I'm a bit surprised 32-bit Window is still buildable. :)

Hello, we noticed  that  at a number  of places in the coding  ,   the  
JNIEXPORT and/or   JNICALL modifiers   do not match  when one compares  the 
declaration and
The implementation of functions.
While this is ok on most platforms, it seems to fail on Windows 32 bit and 
leads to errors like this one :

 : error C2373: 'j2d_mlib_ImageConvKernelConvert' : redefinition; different 
type modifiers
 : see declaration of 'j2d_mlib_ImageConvKernelConvert'

(there are quite a few of these e.g. in mlib  / splashscreen etc.)

Another example is this one :

         jlong* size);

Is there some generic way to get  the  same  declarations / impementations   in 
the code  ?

Or should I just add a patch with my findings ?

Best regards, Matthias
