Yuck, that's a very tangled mess. I'll have to leave that approach for another time.

Instead, I tracked through the commit history (tedious but effective) until I found the offending commit. I had omitted to follow-up on a crucial detail on removing the C99 “PRI64*” macros.

Issue has been resolved with the latest commit: https://github.com/slimcoin-project/Slimcoin/commit/43621ddb701b01e2df36e87113e034a10accaafc

and I have updated the Windows binary slimcoin-qt-v0.5.0-win32.zip listed on the 0.5 release download page

After I've posted this, I'll fire up the Sierra VM, update the OS X app, similarly update the release binary and advertise it here.

I've also discovered the issue with the snapshot - haven't checked the bootstrap yet - it needs be of a datadir for a client that was compiled to use BDB 4.8 - I'll configure my headless client on the server to use BDB 4.8, create a fresh snapshot on the server and also advertise it here.

Cheers

Graham
