Changes for version 0.21
- Fix : context_info() has been taught about perl 5.17.4.
- Fix : t/07-context_info.t will no longer fail with perls that have sitecustomize enabled (like many perl builds for Windows). Thanks Steve Hay and Nicholas Clark for debugging help.
- Fix : Broken linkage on Windows with gcc 3.4, which appears in particular when using ActivePerl's default compiler suite. For those setups, the Scope::Upper shared library will now be linked against the perl dll directly (instead of the import library).
- Scope::Upper - Act on upper scopes.
