This is mostly a work around for the old VC++ problem that it treats func() as func(void). Various prototypes had been added to 'compare' function pointers that triggered this. This could be fixed by removing the prototype, adding function pointer casts to every call or changing the passed function to use the expected arguments. I mostly did the latter. The mkdef.pl script was modified to remove the typesafe functions which no longer exist. Oh and some functions called OPENSSL_freeLibrary() were changed back to FreeLibrary(), wonder how that happened :-)
