I was going to reply with an Ack, but on further consideration,
I'm not sure if we can't do this in general: size_t may be either
'unsigned int' or 'unsigned long' (depending on the architecture
and toolchain), and if kernel and glibc disagree on this, we
have a problem with any user space code that expects sigaltstack->ss_size
to be the same type as size_t (as mandated by the man page).
I wonder if there is another way to address this.
