[MITgcm-support] can't compile checkpoint 63m on Mac OSX

[Martin Losch]

Hi Madeline,

this is what I do in such a case.
1. make sure that I really started from scratch, i.e. 
make makefile && make CLEAN && make depend && make
2. check out different versions of the MITgcm starting from 63j ( in bash:
for version in ( 63j 63k 63l 63m ); do
 cvs co -r checkpoint$version MITgcm_code && mv MITgcm ckpt$version
done
)
and find out when the problem starts.

Also did you try to uncomment
CFLAGS='-arch i386'
?
