Hi Jan, this is the only example that I could find: https://github.com/cran/regRSM/blob/master/DESCRIPTION#L13
I.e. you can have an 'Archs' field in DESCRIPTION, and apparently you can set that to 'i386' or 'x64' or both. I don't know what OSes support this field, and this package hasn't been updated for a while, so I am not 100% sure, but this definitely seems like the proper way to declare a 64-bit only package.
