[MITgcm-support] Run-time errors on Archer

[Dan Jones]

Correction:

The snippet of source code listed above actually comes from yet *another*
error produced if the obcs package is included in packages.conf:

 forrtl: error (63): output conversion error, unit -5, file Internal

      IF ( debugLevel.GE.debLevA ) THEN
        CALL PRINT_LIST_I( OB_Jnorth, 1, OBNS_Nx, INDEX_I,
    &                    .FALSE., .TRUE., standardMessageUnit )

It does *not* come from ini_depths, but from obcs_readparms.  Sorry about
that.
