 > I had committed a fix to jipopt.cpp in r2513 3 weeks ago and now merged
 it to stable/3.11. Is this the one you refer to? Otherwise, please be more
 specific about the "line where a jint* is initialized as an int*".

 Yes, this is exactly the line, sorry.

 headers needed.

 Maybe I wasn't clear enough, it's GCC that doesn't know the type _int64,
 so when using GCC to compile the JNI you need to include inttypes.h and
 use a different but equivalent type.

 I tried it both ways (only fixing the problem with _int64 and replacing
 the typedefs altogether), the error was exactly the same, which is why I
 suspect it's not the cause for this problem.
