It's a harmless message. The Linux sigaction structure has an sa_restorer
field, which is seems weirdly named, and hardly used. If it's used (and
I only know of one application that depends on it), it's more abused.
The Linux emulation has never supported this field before, the only
difference is the message itself, don't worry about it.
