Package: gcc-4.1
Version: 4.1.2-12
Severity: serious

I am not a package maintainer but think that this might be of interest
to you. There appears to be a problem when trying to link static libraries
using gcc on Debian amd64. The linker tries to link gcc (statically?)
and claims that it cannot find libgcc_s. This seems to be true
whether I use the gcc-4.1-multilib packages or other gcc packages available for the and64 platform. Here is an 
example for a simple program that uses libgd (attached)

% gcc -Wl,-Bstatic -lgd -o codehop-gr codehop-gr.c
/usr/bin/ld: cannot find -lgcc_s

The program compiles and works fine if I compile as follows:

% gcc -lgd -o codehop-gr codehop-gr.c
I have experienced the same problem when I remove the gcc-4.1 package and install gcc-4.1-multilib as well as when I have only gcc-3.3 installed. This could be a problem for those who must link against projects that only have static libraries available. 

Thanks for your hard work. -rdb

this is not a bug; you shouldn't fool the driver by bypassing random
linker flags; see gcc(1) for the flags used for statically linking libs.
