I'm not lying, I use <a.h>

Ok, here is the real-life example. Consider

#include <jni.h>

int main(){}

which is compiled with

g++-3.1 -MM -I/opt/JBuilder6/jdk1.3.1/include -I /opt/JBuilder6/jdk1.3.1/include/linux -c a.cc

This gives as the output

a.o: a.cc /opt/JBuilder6/jdk1.3.1/include/jni.h \
  /opt/JBuilder6/jdk1.3.1/include/linux/jni_md.h

I don't want the dependencies on jni.h, as those are system headers.
