[MITgcm-devel] useMNC not in PARAMS.h ?

[Patrick Heimbach]

Ed,

two things:

1. 
Using ifc I don't get a seg. fault,
so this might be a good work around for people
wanting to use mnc.

2.
I think, unrelated to this issue is that, e.g. for
lab_sea, I no longer get monitor output:
grep dynstat output.txt
gives nothing, but
grep dynstat ../results/output.txt\
gives plenty of output.
