alexanderjsummers d6a3afd2a1
Added return value to bool-typed function 
It seems that without this, the build fails with a default Visual C++ on Windows; see https://docs.microsoft.com/en-gb/cpp/error-messages/compiler-warnings/compiler-warning-level-1-c4716 

Another option would be to add the #pragma directive mentioned there.
