Actually it seems this is not the best solution. The issue comes from
the fact on Debian we are having the java installed in
/usr/lib/jvm/default-java, using symlinks. The configure script tries
to follow symlinks to determine the correct include directory.
With OpenJDK, it fails to find it, but it is workarounded by the
following code in debian/rules:
CFLAGS += -I$(JAVA_HOME)/include
With GCJ, after following the symlinks, it is able to find /usr/include
and also include /usr/include/linux as it is a linux system. This
include directory contains headers that conflicts with the GNU libc
headers, hence the strange configure output.
In my opinion the best solution is to avoid following the symlinks on
Debian, as it can gives some strange behaviors later. That's what the
patch below does. I have a test build in progress, currently running
the testsuite.
