I think that's quite exactly what I tried ...

Excellent! I've just tested it with the mob version (last commit
2009-03-21) and it worked!

For some reason I see for every linked object file the following
(warning/error) message:

  new_bind=1 new_shndx=1 new_vis=0 old_bind=1 old_shndx=1 old_vis=0
  ./obj/file1.o: '__va_list_malloc' defined twice
  new_bind=1 new_shndx=1 new_vis=0 old_bind=1 old_shndx=1 old_vis=0
  ./obj/file1.o: '__va_list_free' defined twice

but the resulting library seems to be (more or less - it
certainly needs more testing) okay!


Thanks for your work on the x86-64 target!
