Since we're apparently trying to turn this (originally GWT-specific) question into a catch-all for finding any and all backlinks to a site, here's how to find links to your site from Wikipedia:

Wikipedia

If you want to find out which pages on Wikipedia link to your site (or any site), you can use the Wikipedia external link search.

To search for links to a particular host, like example.com, just type the hostname into the search box, like this. The results will consist of a list of links to the host and the pages they appear on. Note that some of these pages may be talk, user or project pages instead of actual Wikipedia articles.
To search for links to all hostnames in a domain, prepend *. to the search string. For example, this search finds links to example.com and all its subdomains.
Alternatively, to restrict the search to pages under a particular URL path prefix, just include that path in the search. For example, searching for example.com/foo returns links to example.com/foo.html, example.com/foo/bar, example.com/foo.php?id=42 etc.

It seems that you can't combine this restriction with the *. wildcard described above. If you try, the path portion of the search string is ignored.
By default, the search only returns links to http: URLs. To find links to URLs with other schemes, like https: or ftp:, include the scheme you want, followed by //, in your search. You can combine this with either wildcard or path searches.

For example, searching for ftp://*.example.com returns all ftp: links to example.com and any of its subdomains.

For more details, see the documentation on Meta-Wiki.

Note that the link search only finds links from pages on a particular wiki, like the English Wikipedia in the examples above. To find links from Wikipedias in other languages, or from other Wikimedia wikis like Wikimedia Commons, you need to repeat the search on each individual wiki, or use a third-party search front-end like this one.

The link search feature is actually a standard part of the MediaWiki software, and will work also on other sites running MediaWiki, such as Wikia wikis. (Finding the link search page through Wikia's user interface may be tricky, but just going to any page on a wiki and replacing the page name with Special:LinkSearch in the URL should work.) The link search is also available through the MediaWiki API.
