  Testsuite fixes (was Re: [PATCH] Fix libffi on m68k-linux-gnu, completely)
  
  Dixi quod…
  
  >although I believe some 3.0.11 checks to be broken:
  
  And indeed, with a few minor changes on top of git master,
  I still get a full run of PASS plus one XPASS on amd64-linux!
  
  With the other patches (from this message’s parent) and
  these applied, I get a full PASS on m68k-linux as well.
  
  So, please git am these three diffs ☺
  
  bye,

  FWIW, I'm quite impressed with mksh interactively. I thought it was much
  *much* more bare bones. But it turns out it beats the living hell out of
  ksh93 in that respect. I'd even consider it for my daily use if I hadn't
  wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh

  Subject: [PATCH 1/2] Fix tests writing to a closure retval via pointer casts
  
  As explained in <Pine.BSM.4.64L.1212022014490.23442@herc.mirbsd.org>
  all other tests that do the same cast to an ffi_arg pointer instead.
  
  PASS on amd64-linux (Xen domU) and m68k-linux (ARAnyM)
