Hey Thierry,

Without this the struct has the wrong size: sizeof() evaluates

This function is only used in this file. Better to make it static and remove the
declaration from translate.h, which allows you to remove that include.

Add a stubbed-out version of the bsd-user fork's core dump support. This
