/* Open issues:

Missing support for functions returning structs (see TODO in call()).

Missing support for additional data types (64 bit integers, Any, ...; would

trigger assert(false) in various switches).

It is assumed that the variables passed into SbiDllMgr::Call to represent

the arguments and return value have types that exactly match the Declare

signature from the Declare statement, so that it could convert the passed
