  # 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
  # (for the 64-bit ABI).  The same applies to Darwin (DYLD_LIBRARY_PATH),
  # Solaris 32 bit (LD_LIBRARY_PATH_32), Solaris 64 bit (LD_LIBRARY_PATH_64),
  # and HP-UX (SHLIB_PATH).  In some cases, the variables are independent
  # of LD_LIBRARY_PATH, and in other cases LD_LIBRARY_PATH is used if the
  # variable is not defined.
  #
  # Doing this is somewhat of a hack as ld_library_path gets repeated in
  # SHLIB_PATH and LD_LIBRARY_PATH when unix_load sets these variables.
