[Barrelfish-users] [Barrelfish] Question about aliases in flounder

Hi Akhi,

This is another instance of the problem that Flounder wants to "own" the definition of all types, and control their naming. As a workaround, I'd suggest just telling Flounder that the enum values have a suitable integer type (e.g. int32). In the current implementation, it shouldn't make any practical difference to the type safety or efficiency of marshalling.
