Comment 1 Jakub Jelinek 2003-07-31 11:52:00 EDT
Works for me in glibc-2.3.2-56.
Also, it gives a new link time warning:
Using 'initgroups' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
as using NSS/iconv in statically linked programs is really bad idea.
