Hi Pali,

  I must admit that I am reluctant to pursue this feature.  This stub is only
used when running an executable in a DOS environment yes ?  So its utility in
modern Windows based systems seems to be quite small, and implementing it is
likely to introduce new bugs into the linker.

  For the record the function where the hard-coded message is held is
bfd/peicode.h:pe_mkobject().  The message is stored in a 64 byte array in the
pe_data_type structure.  Adding an option to store a custom sequence of 64
bytes into this structure would not be too hard, but I imagine that what you
really want is to be able to store a stub of an arbitrary length.  This would
mean putting in a lot more changes, and would be much more likely to break
things.  This is why I am reluctant to have a go at this.

Cheers
  Nick
