I just compiled the 9.9-dev version from the 12022007 tarball under
  DJGPP. There were only 2 changes needed, one for b_sock.c, since
  DJGPP with WATT32 doesn't define socklen_t and one for testtsa to
  handle DOS style path separators. I also noted what seems to be a
  typographical error in ts.pod. The test suite passes. The patch is
  attached.

  Since I am in the US, I have sent notifications to the Bureau of
  Industry and Security and to the NSA.
