Cool :-)

Well, I assumed that they either create different executables or the 
warnings are known. So I was too lazy to invest the 5 minutes... Sorry 
about that.

But here we go:

/home/Marco/Desktop/compile-lin-lin/gcc-4.2.0-lin-lin/lib/gcc/i686-pc-linux-gnu/4.2.0/../../../libgcj.a(ltdl.o): 
In function `sys_dl_open':

java/net/natInetAddress.cc:153: warning: Using 'gethostbyname_r' in

This warnings occur when compiling a simple System.out.println("hello") 
application with "-static".
