OK. Unfortunately, with the sources I have (20011114), building Java with or
without the patch leads to ICE on my easiest test platform (i686-pc-linux-gnu)
:

../../../src/libjava/jni.cc: In function `T _Jv_JNI_CallAnyMethodV(JNIEnv*, 
   java::lang::Object*, java::lang::Class*, _Jv_Method*, char*) [with T = 
   jfloat, invocation_type style = nonvirtual]':
../../../src/libjava/jni.cc:2600:   instantiated from here
../../../src/libjava/jni.cc:772: Internal compiler error in compensate_edge,
 at reg-stack.c:2564

I'll try on Solaris.

Thanks :)
