Hello,

I run the contrib/download_ecj and rebuilt the java fe 

this time I get this new error when calling : /usr/local2/bin/gcj -save-temps 
Hello.java --main=Hello -v 2>&1 | grep ecj

/usr/local2/libexec/gcc/i686-pc-linux-gnu/4.5.1/ecj1 Hello.java -g1 
-fbootclasspath=./:/usr/local2/share/java/libgcj-4.5.1.jar -g1 -fsource=1.5 
-ftarget=1.5 -fzip-dependency Hello.zip -fzip-target Hello.jar
/usr/local2/libexec/gcc/i686-pc-linux-gnu/4.5.1/ecj1: error while loading shared 
libraries: libgcj_bc.so.1: cannot open shared object file: No such file or 
directory

I think that I did not well rebuild the libgcj, can you specify the instructions 
to do that ?

thank you very much

Asma

Run contrib/download_ecj and rebuild libgcj.
