no, .c (source) files can't be loaded directly, on linux all of anope is compiled from scratch since that s part of default install, on windows you install precompiled exe's and dll's.
so you need to put the compiled version of the .c in data/modules... either you compile it yourself (read [a=http://wiki.anope.org/index.php/Windows:Modules]here[/a] howto) or you download the .dll file for your version (each version of anope will require its own .dll) if the module auther offers then... from a quick look at that site though, he only offers the source for download so you r gonna have to compile it yourself...
i quickly tried it myself with the 0.3B , but it s giving me compile errors on windows... it s annoying enough to get my own modules working on windows so didn't really bother looking into the cause, he probably didn't write the code to compile on windows, just checked it on *nix systems.. you will have to turn to the author for more help
edit: what do you mean doing it into a .dll ... it are completely different file types, you can't just change the extension...
