• Fix : Broken linkage on Windows with gcc 3.4, which appears in
  particular when using ActivePerl's default compiler suite.
  For those setups, the Variable::Magic shared library will now
  be linked against the perl dll directly (instead of the import
  library). This (should) fix RT #51483.
  Thanks Christian Walde for helping to reproduce this failure
  and extra testing.
  
• Rem : Support for development perls from the 5.11 branch but older
  than the 5.11.0 release was removed. This could cause more
  recent setups to fail.
  
• Tst : Threads tests are now only run on perl 5.13.4 and higher.
  They could segfault randomly because of what seems to be an
  internal bug of Perl, which has been addressed in 5.13.4.
  There is also an environment variable that allows you to
  forcefully run those tests, but it should be set only for
  author testing and not for end users.
