[MITgcm-support] RE: MITgcm

[Chris Hill]

 Here is a tar file of mods that should fix things for
darwin_xlf_ppc_panther. The tar file has an updated build_options/ for
genmake2 and an updated "genmake2" and "timers.F" that checks for the etime
function and only generates etime timing code when etim exists.

 I tried this as follows

% cvs co -d MITgcm_HEAD_20040629 MITgcm/
% cd  MITgcm_HEAD_20040629
% tar -xvf ../mods.tar 
% cd verification/global_ocean.90x40x15/build/
% ../../../tools/genmake2
-optfile=../../../tools/build_options/darwin_ppc_xlf_panther -mods=../code
% make depend
% make
% cd ..
% mkdir run
% cd run
% ln -s ../input/* .
% ../build/mitgcmuv >& output
% grep -i cg2d_init ../results/output.txt 
% grep -i cg2d_init output.txt 

 If it works for you we will check it in to our main branch.
