You need to add "-fPIC" to the linker command line  as well. If any of
your  *.o files  contain  static CTOR/DTORs, a   small .c file will be
generated by the  collect2 program which  in turn will be compiled and
linked into  your shared lib.  Since you  didn't specify "-fPIC"  when
linking, bloody  StunOS ld starts complaining...  Of course, using GNU
ld (e.g. from  binutils-2.9.1) would cure  this; the current  mainline
sources (the  snapshots)  address  this   differently, i.e.  you   can
continue using SunOS ld.
