In the branch https://github.com/phaverty/rjulia I have various julia 0.5 changes going, but you may find the changes to the MakeVars file and the Windows-only code useful independent of the other changes. I used the example in Julia's new embedding documentation to figure out what all the compile flags should be. This fixes a compile-time error on 0.5.
The required code for marking something Windows-only changed and I followed the suggestion in julia's warning message.
