[21.4] Patch for consistent crash with Linux native sound on AMD64

[Hans de Graaff]

On my AMD64 machine I can crash XEmacs 21.4.20 consistently by starting
xemacs and doing two page-ups. I'm using Linux native sound right now, and
that seems to be the problem. (I remember this crash from .19 as well but
didn't have time to investigate then.)

The following patch fixes things for me and makes sense since prtn and rrtn
are later recast as a size_t.

Kind regards,

Hans
