If the dll already loaded, then there is no harm at all. But if not,
there is huge penalty in performance and memory usage. Take into account
that currently built-in dlls are never unloaded. In the case of oleaut32,
ole32 and advapi32 also will be loaded. If an application doesn't use them,
but simply does query its version, there is more harm, than the good.

Strange, I tested my patch with About.exe and it worked for me.

You could try replace version.rc by the following version resource, and
to see if it will help (even better try to use both and report the result):
