in the Debian package of OpenMPI there has been a patch  for some
time which I think is obsolete. I did some reading on that topic but I'm
not very familiar with assembler, so I'm asking you here.
As far as I can see, removing the patch doesn't change the binaries
much. Neither scanelf nor readelf show something I'd consider as
suspicious. I think that the .note.GNU-stack instruction is added to the
assembler files by generate-asm.pl, so everything's set properly.
But as I said, I'm not very familiar with the matter and it would be
great to get a statement on that issue from you. (We could drop a rather
large patch along with this one, if it's obsolete.) Thanks in advance!
