[MITgcm-support] namelist; end of file reached without finding group

[Jean-Michel Campin]

Hi Matt,

I am going to check-in your modifs, with a small difference:
TARGET_BGL or TARGET_CRAYXT would need to be specified either as a cpp flag 
 (e.g. in our optfile, by adding -DTARGET_BGL to DEFINES list), 
or by adding "#defined TARGET_BGL" in our CPP_EEOPTIONS.h (and not 
CPP_OPTIONS.h).

I am not going to change "eesupp/src/nml_filter.F" since I don't
find any call to this subroutine. Patrick, may be we should remove it ?

Also, will not be able to really test this, so if you could give it a try.

Thanks,
Jean-Michel
