Looks good Dave!

Could I ask you to also remove the -diag-disable 5140 flag in these files:

$ git grep -l ' 5140'
configuration/scripts/machines/Macros.banting_intel
configuration/scripts/machines/Macros.cesium_intel
configuration/scripts/machines/Macros.daley_intel
configuration/scripts/machines/Macros.millikan_intel

Since it won't be needed now that these directives are removed :)
