Fix for compile problem in rpc/mining.cpp on some platforms
Summary
Addresses issue #195 (closed). Recent change in MR !867 (merged) boldly attempted to go
where no return type has gone before in this codebase and use auto
and
some compilers were not happy. Clang on Darwin namely. See issue.
Test Plan
ninja check check-functional
- Optional: If you have access to a Darwin system, ensure it compiles there. I am not sure if this problem also manifests itself on clang on Linux, so maybe it would be nice to try building on clang on Linux too as a check as well.
