File#link and File#symlink break hard on Windows
------------------------------------------------
Key: JRUBY-1921
URL: http://jira.codehaus.org/browse/JRUBY-1921
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC1
Environment: Latest JRuby 1.1RC1
Reporter: Vladimir Sizikov
Attachments: file-link-symlink-broken-windows.patch
The following lines:
{noformat}
File.link("blah", "blah.lnk")
File.symlink("blah", "blah.lnk")
{noformat}
break JRuby hard, with exception:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot locate
function 'link'

At a minimum, invocation of File#link and File#symlink should not break, but
rather should
throw NotImplementedError.
The proposed patch fixes the problem.
