Hi Ben, I observed warnings of this kind in a couple of places building head yesterday: ``` compiler/utils/FastString.hs:336:5: error: warning: 'GHC_STAGE' is not defined, evaluates to 0 [-Wundef] | 336 | #if GHC_STAGE < 2 | ^ #if GHC_STAGE < 2 ^ ``` ``` compiler/main/DynFlags.hs:323:5: error: warning: 'GHC_STAGE' is not defined, evaluates to 0 [-Wundef] | 323 | #if GHC_STAGE >= 2 | ^ #if GHC_STAGE >= 2 ^ ``` I was using the `hadrian/build.stack.sh` approach. Figured you'd want to know! -- *Shayne Fletcher* Language Engineer */* +1 917 699 7663 *Digital Asset* https://digitalasset.com/, creators of *DAML https://daml.com/* -- This message, and any attachments, is for the intended recipient(s) only, may contain information that is privileged, confidential and/or proprietary and subject to important terms and conditions available at http://www.digitalasset.com/emaildisclaimer.html http://www.digitalasset.com/emaildisclaimer.html.
