Jesus ! And only one answer posted on known thing ?

Thank you, Elena !

So what to do in my case now ? I have projects reverted from gcc-2.95 
and old automake/autoconf because I have believed that gcc-3.2/gdb-5.2.x 
is better combination !

1. Revert to use of the gcc-2.95/gdb3/4 or what ?
2. Put all kinds of outputs throughout the tons of the shared libs to 
make the debugging stoneage way ?
3. Or somebody (maybe A.Cagney) will appoint me to the right solution - 
I really doubt that there is no one !


Is this behaviour also the case with the gdb-5.3 ? I have tried to 
compile it with my gcc-3.2 and it requests the libterm library which I 
do not have in my SuSE 8.1 distro. I will not even try again if this 
mess with the debugging info is the same in gdb-5.3 !
