That is correct.

Sorry for not having looked at this earlier, I just realized that this
is a mistake
in user space: uapi headers are not allowed to reference CONFIG_* symbols,
since the headers are supposed to be configuration independent and the
CONFIG_* namespace might clash with user space identifiers.

The correct check appears to be

#if defined(__sparc__) && defined(__arch64__)

This is required for the proper functioning of the y2038 additions to input 
event.
