gcj bug with locale (was: gcj with date manip. ...)

So because I had a problem with gcj-2.97, I've finaly been
able to build a version of gcc-3.0 both on linuppc
(with --enable-languages=c++,java) and and linux intel
(with --enable-languages=c++,java,f77)
But the same error occured when using Date.toString() method.
This result occured on linux distribution (both intel anf
linuxppc) with the following locale in my .cshrc:
setenv LC_ALL fr_FR
but all work fine if all replace this with:
setenv LC_ALL en_US.iso-8859-1
But now, all my application menu are in english
(and as you can see, I'm not very clever in english :-)
I think this is a bug from gcc which should use default
locale such as "en_US.iso-8859-1" in replacement of
"fr_FR.iso-8859-1" instead of rising an exception.
But now, I can keep on working with gcj instead of javac...
Thank you very much!

If you are yet interested by this problem, here
is the full trace af it :
--------------------------------------------------------------
Here is the program (about the same than previous):
import java.util.*;
import java.text.SimpleDateFormat;
public class Test {
public static void main(String[] args) {
// this work
Date date = new Date();
System.out.println ("getTime=" + date.getTime());
// this doesn't work
System.out.println ("date=" + date.toString());
// this doesn't work neither !!
SimpleDateFormat df =
new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss.SSSS");
System.out.println ("Début à: " + df.format(date) );
return;
}
}
------------------------------------------------------------
Here is the jdk result:
>javac Test.java && java Test
getTime=984043770064
date=Thu Mar 08 10:29:30 CET 2001
Début à: 2001年03月08日 10:29:30.0064
------------------------------------------------------------
Here is the gcj result:
>gcj -O0 -g --main=Test -o test Test.java
(nota: make .class first, the making test rise the same error)
I replace "/usr/local/pack/gcc-3.0-cvs-20010306/powerpc-linux/"
by "//" for readability
./test

Then Here the result from gdb
----------------------------
A - If dynamicaly compiled :
(gdb) run
Starting program: /home/diam/projets/jorlab/benchs_java/testbug/test
/home/diam/projets/jorlab/benchs_java/testbug/test: error in loading shared libraries: libgcc_s.so.0: cannot open shared object file: No such file or directory
Program exited with code 0177.
But the LB_LIBRARY_PATH is well set!!!
----------------------------
B - So I compiled with -static
(and setenv CLASSPATH .../share/libgcj.jar)
