State-Changed-Why:
    Thanks for your report.
    
    I believe this problem is fixed in the most recent gcj
    release (gcc 3.2).  Now the CNI definitions for jobject
    and the like are visible only to the libgcj implementation
    itself; user programs using our <jni.h> should work just
    as they would with Sun's header.
    
    If you try this and it turns out to have a problem, we
    can reopen this PR.

>Description:
I have a JNI program that works fine when I build it from make.  However, when I build it using Ant, g++ starts treating my JNI natives (jobject, jstring, jthrowable) as stuff from javaprims.h (java::lang::Object, java::lang::String, java::lang::Throwable).
It seems as though it thinks that since its being invoked from a Java process, it has the right to use the GCJ stuff.  I know this because I can copy/paste the output from ant into an xterm and it compiles fine.
>How-To-Repeat:
Get some JNI code and try to compile it with g++ from Ant.
>Fix:
Don't try to invoke g++ from within a Java process...  WTF is up with that?
