- Now using double underscores for generated module names, for better
  interaction with -short-paths and to avoid conflict with user-defined
  names (reported Thomas Refis, Florian Angeletti).
- Fixed circular dependency when building libraries.
- Added workaround for building libraries with Namespaces and OASIS.
- Fixed tags not being copied over from original files to generated
  files.
