Hello! Looking deep into Mozilla's LiveConnect sources (under mozilla/sun-java/stubs/include/) I gather, jint really wants to be intptr_t -- not a mere int as, for example, jdk1.5.0/include/freebsd/jni_md.h makes it out to be. Can anyone comment? Thanks! -mi P.S. Obviously, I'm trying to make things work perfectly on amd64 :-)
