  # We need to set ld library path in the environment.  Currently,
  # unix.exp doesn't set the environment correctly for all systems.
  # It only sets SHLIB_PATH and LD_LIBRARY_PATH when it executes a
  # program.  We also need the environment set for compilations, etc.
  #
  # On IRIX 6, we have to set variables akin to LD_LIBRARY_PATH, but
  # called LD_LIBRARYN32_PATH (for the N32 ABI) and LD_LIBRARY64_PATH
