I think you're missing the point - you should be fixing that file instead - it doesn't matter whether you're on Windows or not. If the file is created automatically then it has no business being in the package. Otherwise you should simply post-process it (e.g., as Dirk suggested) after it has been generated but before you create the package - that is the common practice with generated files that need to be part of the distribution.

Cheers,
Simon
