>Environment:
System: Linux utx 2.4.0-test10 #20 Èt lis 2 10:33:45 CET 2000 i686 unknown
Architecture: i686
glibc-2.1.3
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
>Description:
Any shared object linked with recent gcc against glibc-2.1.3 fails:
error in loading shared libraries: foo.so: undefined symbol: __dso_handle
After upgrade to glibc-2.2pre gcc compiles shared objects OK.

>How-To-Repeat:
Link any shared object in upper mentioned environment.
>Fix:
__dso_handle was introduced in glibc-2.2pre and seems not to be present in glibc-2.1.x.
