Yes, that's really puzzling.  I can reproduce the issue, but it's
pretty unclear what happens.  When extracting the resources from
the linked executable, for instance with

  windres dlg_one.out -o dlg_from_exe.rc

the resulting rc file looks perfectly normal.  Maybe this has
something to do with alignment?!?

Would you mind to create a bugzilla entry for this problem at ?
