Hi Dan,

Regarding the confusion, it's my fault, I quoted the g77 output instead of
the gfortran output !

However, I did not check last time but the OpenAD output has changes too:
from March 19:
Y Y Y Y 16>10<16 FAIL  halfpipe_streamice
and before your changes (e.g., March 18):
Y Y Y Y 16>16<16 pass  halfpipe_streamice
Could you check this one and update output_oadm.txt if you think these
changes are expected ?

And coming back to TAF adm, it's not clear if results did change or not
since the output_adm.txt had not been updated (after changes made at the end
of June 2015 or in July 2015) with only 10 digits agreement since that time:
Y Y Y Y 12>10< 5 FAIL  halfpipe_streamice  (e=0, w=8)
Should I update this output_adm.txt (agreement between fwd grad and AD grad
are not significantly different) ? 

Cheers,
Jean-Michel
