Subject:   -54- Why don't COFF executables run on IRIX 6.1 or 6.2?

  IRIX 6.1 has kernel support for COFF executables, but does not have
  the shared libraries. If you copy the shared libraries from an IRIX
  5.3 system to your IRIX 6.1 system your COFF executable should work.
  IRIX 6.2 does not have kernel support for COFF.
