Subject: [PATCH] Apply a patch from Gisle Vanem to make tor-gencert build
 under MSVC

(Note: It makes sense to use tor-gencert on Windows for testing
purposes only.  If you are a directory authority operator, and you
are contemplating running tor-gencert on a Windows box in an actual
production environment, you are probably making a mistake.)
