      Description

      Current Ticket Scope:
      Although the `queryableWtFsCreate` method is not mangled (extern "C"), that is not sufficient for exporting the symbol on windows for a dynamic function load.

      Original ticket description (was configuration error):
      MongoDB 3.4.9 with the queryable_wt engine fails to come up on Windows.

      Command: mongodb-win32-x86_64-enterprise-windows-64-3.4.9\bin\mongod.exe --config .\test_dbs\queryable\59db7af3686b370558ba4519\dbpath/conf.yaml

      ***aborting after fassert() failure
      

      This could be a yaml formatting issue. I tried to rule out the "/" vs. "\" in paths as the cause, but all led to the same fasserts.
