The reproNative project has the secure vcproj defaults, passes /SAFESEH to the linker and linker complains that the inputs are not annotated with SAFESEH.
We should get the obj inputs annotated correctly (looks like it will require change in the obj writer) and pass SAFESEH to the linker on win-x86 to avoid compliance warnings from tools like https://github.com/microsoft/binskim
